/**
* Create a new Popper.js instance
* @constructor Popper
* @param {HTMLElement} reference - The reference element used to position the popper
* @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).
*
* @param {String|Element} [options.boundariesElement='viewport']
* The element which will define the boundaries of the popper position, the popper will never be placed outside
* of the defined boundaries (except if `keepTogether` is enabled)
*
* @param {Number} [options.boundariesPadding=5]
* 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
* The function should reflect the @params and @returns of preventOverflow
*
* @param {Boolean} [options.removeOnDestroy=false]
* Set to true if you want to automatically remove the popper when you call the `destroy` method.

* 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:
* `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
* `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`,
* `commit`, `compact`, `concat`, `conforms`, `constant`, `countBy`, `create`,
* `curry`, `debounce`, `defaults`, `defaultsDeep`, `defer`, `delay`,
* `difference`, `differenceBy`, `differenceWith`, `drop`, `dropRight`,
* `dropRightWhile`, `dropWhile`, `extend`, `extendWith`, `fill`, `filter`,
* `flatMap`, `flatMapDeep`, `flatMapDepth`, `flatten`, `flattenDeep`,
* `flattenDepth`, `flip`, `flow`, `flowRight`, `fromPairs`, `functions`,
* `functionsIn`, `groupBy`, `initial`, `intersection`, `intersectionBy`,
* `intersectionWith`, `invert`, `invertBy`, `invokeMap`, `iteratee`, `keyBy`,
* `keys`, `keysIn`, `map`, `mapKeys`, `mapValues`, `matches`, `matchesProperty`,
* `memoize`, `merge`, `mergeWith`, `method`, `methodOf`, `mixin`, `negate`,

* `pickBy`, `plant`, `property`, `propertyOf`, `pull`, `pullAll`, `pullAllBy`,
* `pullAllWith`, `pullAt`, `push`, `range`, `rangeRight`, `rearg`, `reject`,
* `remove`, `rest`, `reverse`, `sampleSize`, `set`, `setWith`, `shuffle`,
* `slice`, `sort`, `sortBy`, `splice`, `spread`, `tail`, `take`, `takeRight`,

* `valuesIn`, `without`, `wrap`, `xor`, `xorBy`, `xorWith`, `zip`,
* `zipObject`, `zipObjectDeep`, and `zipWith`
*
* The wrapper methods that are **not** chainable by default are:
* `add`, `attempt`, `camelCase`, `capitalize`, `ceil`, `clamp`, `clone`,
* `cloneDeep`, `cloneDeepWith`, `cloneWith`, `conformsTo`, `deburr`,
* `defaultTo`, `divide`, `each`, `eachRight`, `endsWith`, `eq`, `escape`,
