// The spans will have null for their from/to properties when the
// marker continues beyond the start/end of the line. Markers have
// links back to the lines they currently touch.

     * @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]

    /**
     * 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`,

    /**
     * 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`,
