/**
 * 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`,

 * Provide `options` to indicate whether `func` should be invoked on the
 * leading and/or trailing edge of the `wait` timeout. The `func` is invoked
 * with the last arguments provided to the debounced function. Subsequent
 * calls to the debounced function return the result of the last `func`

 *
 * **Note:** If `leading` and `trailing` options are `true`, `func` is
 * invoked on the trailing edge of the timeout only if the debounced function
 * is invoked more than once during the `wait` timeout.
 *
 * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
 * until to the next tick, similar to `setTimeout` with a timeout of `0`.
