* 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`,
* `curry`, `debounce`, `defaults`, `defaultsDeep`, `defer`, `delay`,
* `difference`, `differenceBy`, `differenceWith`, `drop`, `dropRight`,
* `dropRightWhile`, `dropWhile`, `extend`, `extendWith`, `fill`, `filter`,
* `flatMap`, `flatMapDeep`, `flatMapDepth`, `flatten`, `flattenDeep`,
* `flattenDepth`, `flip`, `flow`, `flowRight`, `fromPairs`, `functions`,
* `functionsIn`, `groupBy`, `initial`, `intersection`, `intersectionBy`,
* `intersectionWith`, `invert`, `invertBy`, `invokeMap`, `iteratee`, `keyBy`,
* `keys`, `keysIn`, `map`, `mapKeys`, `mapValues`, `matches`, `matchesProperty`,
* `memoize`, `merge`, `mergeWith`, `method`, `methodOf`, `mixin`, `negate`,

* `valuesIn`, `without`, `wrap`, `xor`, `xorBy`, `xorWith`, `zip`,
* `zipObject`, `zipObjectDeep`, and `zipWith`
*
* The wrapper methods that are **not** chainable by default are:
* `add`, `attempt`, `camelCase`, `capitalize`, `ceil`, `clamp`, `clone`,
* `cloneDeep`, `cloneDeepWith`, `cloneWith`, `conformsTo`, `deburr`,
