/**
 * 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`, `mapKeys`, `mapValues`, `matches`, `matchesProperty`,
 * `memoize`, `merge`, `method`, `methodOf`, `mixin`, `negate`, `omit`, `once`,
 * `pairs`, `partial`, `partialRight`, `partition`, `pick`, `plant`, `pluck`,
 * `property`, `propertyOf`, `pull`, `pullAt`, `push`, `range`, `rearg`,
 * `reject`, `remove`, `rest`, `restParam`, `reverse`, `set`, `shuffle`,
 * `slice`, `sort`, `sortBy`, `sortByAll`, `sortByOrder`, `splice`, `spread`,
 * `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `tap`, `throttle`,
 * `thru`, `times`, `toArray`, `toPlainObject`, `transform`, `union`, `uniq`,
 * `unshift`, `unzip`, `unzipWith`, `values`, `valuesIn`, `where`, `without`,
 * `wrap`, `xor`, `zip`, `zipObject`, `zipWith`
 *
 * 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`, `get`,
 * `gt`, `gte`, `has`, `identity`, `includes`, `indexOf`, `inRange`, `isArguments`,
 * `isArray`, `isBoolean`, `isDate`, `isElement`, `isEmpty`, `isEqual`, `isError`,
 * `isFinite` `isFunction`, `isMatch`, `isNative`, `isNaN`, `isNull`, `isNumber`,
 * `isObject`, `isPlainObject`, `isRegExp`, `isString`, `isUndefined`,
 * `isTypedArray`, `join`, `kebabCase`, `last`, `lastIndexOf`, `lt`, `lte`,
 * `max`, `min`, `noConflict`, `noop`, `now`, `pad`, `padLeft`, `padRight`,
 * `parseInt`, `pop`, `random`, `reduce`, `reduceRight`, `repeat`, `result`,

 * `sortedLastIndex`, `startCase`, `startsWith`, `sum`, `template`, `trim`,
 * `trimLeft`, `trimRight`, `trunc`, `unescape`, `uniqueId`, `value`, and `words`
