/**
* 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.
