 * Creates a `lodash` object which wraps `value` to enable implicit chaining.
 * 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 returning the unwrapped
 * value. Explicit chaining may be enabled using `_.chain`. The execution of
 * chained methods is lazy, that is, execution is deferred until `_#value`
 * is implicitly or explicitly called.
 *
 * Lazy evaluation allows several methods to support shortcut fusion. Shortcut
 * fusion is an optimization strategy which merge iteratee calls; this can help
 * to avoid the creation of intermediate data structures and greatly reduce the
 * number of iteratee executions.
 *
 * 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.

 * `slice`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `toArray`,
 * and `where`
 *

 * `after`, `ary`, `assign`, `at`, `before`, `bind`, `bindAll`, `bindKey`,
 * `callback`, `chain`, `chunk`, `commit`, `compact`, `concat`, `constant`,
 * `countBy`, `create`, `curry`, `debounce`, `defaults`, `defaultsDeep`,
