     * @param {HTMLElement|Object} popper
     *      The HTML element used as popper, or a configuration used to generate the popper.
     * @param {String} [popper.tagName='div'] The tag name of the generated popper.
     * @param {Array} [popper.classNames=['popper']] Array of classes to apply to the generated popper.
     * @param {Array} [popper.attributes] Array of attributes to apply, specify `attr:value` to assign a value to it.
     * @param {HTMLElement|String} [popper.parent=window.document.body] The parent element, given as HTMLElement or as query string.
     * @param {String} [popper.content=''] The content of the popper, it can be text, html, or node; if it is not text, set `contentType` to `html` or `node`.
     * @param {String} [popper.contentType='text'] If `html`, the `content` will be parsed as HTML. If `node`, it will be appended as-is.
     * @param {String} [popper.arrowTagName='div'] Same as `popper.tagName` but for the arrow element.
     * @param {Array} [popper.arrowClassNames='popper__arrow'] Same as `popper.classNames` but for the arrow element.
     * @param {String} [popper.arrowAttributes=['x-arrow']] Same as `popper.attributes` but for the arrow element.
     * @param {Object} options
     * @param {String} [options.placement=bottom]
     *      Placement of the popper accepted values: `top(-start, -end), right(-start, -end), bottom(-start, -right),
     *      left(-start, -end)`
     *
     * @param {HTMLElement|String} [options.arrowElement='[x-arrow]']
     *      The DOM Node used as arrow for the popper, or a CSS selector used to get the DOM node. It must be child of
     *      its parent Popper. Popper.js will apply to the given element the style required to align the arrow with its
     *      reference element.
     *      By default, it will look for a child node of the popper with the `x-arrow` attribute.
     *
     * @param {Boolean} [options.gpuAcceleration=true]
     *      When this property is set to true, the popper position will be applied using CSS3 translate3d, allowing the
     *      browser to use the GPU to accelerate the rendering.
     *      If set to false, the popper will be placed using `top` and `left` properties, not using the GPU.
     *
     * @param {Number} [options.offset=0]
     *      Amount of pixels the popper will be shifted (can be negative).
     *

     *      Additional padding for the boundaries
     *
     * @param {Array} [options.preventOverflowOrder=['left', 'right', 'top', 'bottom']]
     *      Order used when Popper.js tries to avoid overflows from the boundaries, they will be checked in order,
     *      this means that the last ones will never overflow
     *
     * @param {String|Array} [options.flipBehavior='flip']
     *      The behavior used by the `flip` modifier to change the placement of the popper when the latter is trying to
     *      overlap its reference element. Defining `flip` as value, the placement will be flipped on
     *      its axis (`right - left`, `top - bottom`).
     *      You can even pass an array of placements (eg: `['right', 'left', 'top']` ) to manually specify
     *      how alter the placement when a flip is needed. (eg. in the above example, it would first flip from right to left,
     *      then, if even in its new placement, the popper is overlapping its reference element, it will be moved to top)
     *
     * @param {Array} [options.modifiers=[ 'shift', 'offset', 'preventOverflow', 'keepTogether', 'arrow', 'flip', 'applyStyle']]
     *      List of functions used to modify the data before they are applied to the popper, add your custom functions
     *      to this array to edit the offsets and placement.
     *      The function should reflect the @params and @returns of preventOverflow
     *
     * @param {Array} [options.modifiersIgnored=[]]
     *      Put here any built-in modifier name you want to exclude from the modifiers list

    /**
     * Creates a `lodash` object which wraps `value` to enable implicit method
     * chain sequences. Methods that operate on and return arrays, collections,
     * and functions can be chained together. Methods that retrieve a single value
     * or may return a primitive value will automatically end the chain sequence
     * and return the unwrapped value. Otherwise, the value must be unwrapped
     * with `_#value`.
     *
     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
     * enabled using `_.chain`.
     *
     * The execution of chained methods is lazy, that is, it's deferred until
     * `_#value` is implicitly or explicitly called.
     *
     * Lazy evaluation allows several methods to support shortcut fusion.
     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
     * the creation of intermediate arrays and can greatly reduce the number of
     * iteratee executions. Sections of a chain sequence qualify for shortcut
     * fusion if the section is applied to an array and iteratees accept only
     * one argument. The heuristic for whether a section qualifies for shortcut
     * fusion is subject to change.
     *
     * Chaining is supported in custom builds as long as the `_#value` method is
     * directly or indirectly included in the build.
     *
     * In addition to lodash methods, wrappers have `Array` and `String` methods.
     *
     * The wrapper `Array` methods are:
     * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
     *
     * The wrapper `String` methods are:
     * `replace` and `split`
     *
     * The wrapper methods that support shortcut fusion are:

     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
     *
     * The chainable wrapper methods are:
     * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
     * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,

/**
 *  Provides entirely client-side User Agent and OS detection. You should prefer

 *
 *  Usage is straightforward:
 *
 *    if (UserAgent_DEPRECATED.ie()) {
 *      //  IE
 *    }
 *
 *  You can also do version checks:
 *
 *    if (UserAgent_DEPRECATED.ie() >= 7) {
 *      //  IE7 or better
 *    }
 *
 *  The browser functions will return NaN if the browser does not match, so
 *  you can also do version compares the other way:
 *
 *    if (UserAgent_DEPRECATED.ie() < 7) {
 *      //  IE6 or worse
 *    }
 *
 *  Note that the version is a float and may include a minor version number,
 *  so you should always use range operators to perform comparisons, not
 *  strict equality.
 *
 *  **Note:** You should **strongly** prefer capability detection to browser
 *  version detection where it's reasonable:
 *
 *    http://www.quirksmode.org/js/support.html
 *
 *  Further, we have a large number of mature wrapper functions and classes
 *  which abstract away many browser irregularities. Check the documentation,
 *  grep for things, or ask on javascript@lists.facebook.com before writing yet
 *  another copy of "event || window.event".

/**
 * Mouse wheel (and 2-finger trackpad) support on the web sucks.  It is
 * complicated, thus this doc is long and (hopefully) detailed enough to answer
 * your questions.
 *
 * If you need to react to the mouse wheel in a predictable way, this code is
 * like your bestest friend. * hugs *
 *
 * As of today, there are 4 DOM event types you can listen to:
 *
 *   'wheel'                -- Chrome(31+), FF(17+), IE(9+)
 *   'mousewheel'           -- Chrome, IE(6+), Opera, Safari
 *   'MozMousePixelScroll'  -- FF(3.5 only!) (2010-2013) -- don't bother!
 *   'DOMMouseScroll'       -- FF(0.9.7+) since 2003
 *
 * So what to do?  The is the best:
 *
 *   normalizeWheel.getEventType();
 *
 * In your event callback, use this code to get sane interpretation of the
 * deltas.  This code will return an object with properties:
 *
 *   spinX   -- normalized spin speed (use for zoom) - x plane
 *   spinY   -- " - y plane
 *   pixelX  -- normalized distance (to pixels) - x plane
 *   pixelY  -- " - y plane
 *
 * Wheel values are provided by the browser assuming you are using the wheel to
 * scroll a web page by a number of lines or pixels (or pages).  Values can vary
 * significantly on different platforms and browsers, forgetting that you can
 * scroll at different speeds.  Some devices (like trackpads) emit more events
 * at smaller increments with fine granularity, and some emit massive jumps with
 * linear speed or acceleration.
 *
 * This code does its best to normalize the deltas for you:
 *
 *   - spin is trying to normalize how far the wheel was spun (or trackpad
 *     dragged).  This is super useful for zoom support where you want to
 *     throw away the chunky scroll steps on the PC and make those equal to
 *     the slow and smooth tiny steps on the Mac. Key data: This code tries to
 *     resolve a single slow step on a wheel to 1.
 *
 *   - pixel is normalizing the desired scroll delta in pixel units.  You'll
 *     get the crazy differences between browsers, but at least it'll be in
 *     pixels!
 *
 *   - positive value indicates scrolling DOWN/RIGHT, negative UP/LEFT.  This
 *     should translate to positive value zooming IN, negative zooming OUT.
 *     This matches the newer 'wheel' event.
 *
 * Why are there spinX, spinY (or pixels)?
 *
 *   - spinX is a 2-finger side drag on the trackpad, and a shift + wheel turn
 *     with a mouse.  It results in side-scrolling in the browser by default.
 *
 *   - spinY is what you expect -- it's the classic axis of a mouse wheel.
 *
 *   - I dropped spinZ/pixelZ.  It is supported by the DOM 3 'wheel' event and
 *     probably is by browsers in conjunction with fancy 3D controllers .. but
 *     you know.
 *
 * Implementation info:
 *
 * Examples of 'wheel' event if you scroll slowly (down) by one step with an
 * average mouse:
 *
 *   OS X + Chrome  (mouse)     -    4   pixel delta  (wheelDelta -120)
 *   OS X + Safari  (mouse)     -  N/A   pixel delta  (wheelDelta  -12)
 *   OS X + Firefox (mouse)     -    0.1 line  delta  (wheelDelta  N/A)
 *   Win8 + Chrome  (mouse)     -  100   pixel delta  (wheelDelta -120)
 *   Win8 + Firefox (mouse)     -    3   line  delta  (wheelDelta -120)
 *
 * On the trackpad:
 *
 *   OS X + Chrome  (trackpad)  -    2   pixel delta  (wheelDelta   -6)
 *   OS X + Firefox (trackpad)  -    1   pixel delta  (wheelDelta  N/A)
 *
 * On other/older browsers.. it's more complicated as there can be multiple and
 * also missing delta values.
 *
 * The 'wheel' event is more standard:
 *
 * http://www.w3.org/TR/DOM-Level-3-Events/#events-wheelevents
 *
 * The basics is that it includes a unit, deltaMode (pixels, lines, pages), and
 * deltaX, deltaY and deltaZ.  Some browsers provide other values to maintain
 * backward compatibility with older events.  Those other values help us
 * better normalize spin speed.  Example of what the browsers provide:
 *
 *                          | event.wheelDelta | event.detail
 *        ------------------+------------------+--------------
 *          Safari v5/OS X  |       -120       |       0
 *          Safari v5/Win7  |       -120       |       0
 *         Chrome v17/OS X  |       -120       |       0
 *         Chrome v17/Win7  |       -120       |       0
 *                IE9/Win7  |       -120       |   undefined
 *         Firefox v4/OS X  |     undefined    |       1
 *         Firefox v4/Win7  |     undefined    |       3
