-//	1. Enforce API surface and semantic compatibility with 1.9.x branch
-//	2. Improve the module's maintainability by reducing the storage
-//		paths to a single mechanism.
-//	3. Use the same single mechanism to support "private" and "user" data.
-//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
-//	5. Avoid exposing implementation details on user objects (eg. expando properties)
-//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

-     * 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.

-   * The `offset` modifier can shift your popper on both its axis.
-   *
-   * It accepts the following units:
-   * - `px` or unit-less, interpreted as pixels
-   * - `%` or `%r`, percentage relative to the length of the reference element
-   * - `%p`, percentage relative to the length of the popper element

-   * This means that if the placement is `top` or `bottom`, the length will be the
-   * `width`. In case of `left` or `right`, it will be the `height`.
-   *
-   * You can provide a single value (as `Number` or `String`), or a pair of values
-   * as `String` divided by a comma or one (or more) white spaces.<br />
-   * The latter is a deprecated method because it leads to confusion and will be
-   * removed in v2.<br />
-   * Additionally, it accepts additions and subtractions between different units.
-   * Note that multiplications and divisions aren't supported.
-   *
-   * Valid examples are:
-   * ```
-   * 10
-   * '10%'
-   * '10, 10'
-   * '10%, 10'
-   * '10 + 10%'
-   * '10 - 5vh + 3%'
-   * '-10px + 5vh, 5px - 6%'
-   * ```
-   * > **NB**: If you desire to apply offsets to your poppers in a way that may make them overlap

-       * 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:

-       * `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:

+     *
+     * 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`
+     *
