/**
* 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 return a boolean or single 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 that merges iteratees to avoid creating intermediate
* arrays and 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.
*
* The wrapper `Array` methods are:
* `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`,
* `splice`, and `unshift`
*
* The wrapper `String` methods are:
* `replace` and `split`
*
* The wrapper methods that support shortcut fusion are:
* `compact`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `filter`,
* `first`, `initial`, `last`, `map`, `pluck`, `reject`, `rest`, `reverse`,
* `slice`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `toArray`,
* and `where`
*
* The chainable wrapper methods are:
* `after`, `ary`, `assign`, `at`, `before`, `bind`, `bindAll`, `bindKey`,
* `callback`, `chain`, `chunk`, `commit`, `compact`, `concat`, `constant`,
* `countBy`, `create`, `curry`, `debounce`, `defaults`, `defer`, `delay`,
* `difference`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `fill`,
* `filter`, `flatten`, `flattenDeep`, `flow`, `flowRight`, `forEach`,
* `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`, `functions`,
* `groupBy`, `indexBy`, `initial`, `intersection`, `invert`, `invoke`, `keys`,
* `keysIn`, `map`, `mapValues`, `matches`, `matchesProperty`, `memoize`, `merge`,
* `mixin`, `negate`, `noop`, `omit`, `once`, `pairs`, `partial`, `partialRight`,
* `partition`, `pick`, `plant`, `pluck`, `property`, `propertyOf`, `pull`,
* `pullAt`, `push`, `range`, `rearg`, `reject`, `remove`, `rest`, `reverse`,
* `shuffle`, `slice`, `sort`, `sortBy`, `sortByAll`, `sortByOrder`, `splice`,
* `spread`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `tap`,

* `union`, `uniq`, `unshift`, `unzip`, `values`, `valuesIn`, `where`,
* `without`, `wrap`, `xor`, `zip`, and `zipObject`
*
* The wrapper methods that are **not** chainable by default are:
* `add`, `attempt`, `camelCase`, `capitalize`, `clone`, `cloneDeep`, `deburr`,
* `endsWith`, `escape`, `escapeRegExp`, `every`, `find`, `findIndex`, `findKey`,
* `findLast`, `findLastIndex`, `findLastKey`, `findWhere`, `first`, `has`,
