   * 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 also have the following `Array` methods:
   * `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`, `splice`,
   * and `unshift`
   *
   * 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`, `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`, `splice`, `spread`,
   * `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `tap`, `throttle`,
   * `thru`, `times`, `toArray`, `toPlainObject`, `transform`, `union`, `uniq`,
   * `unshift`, `unzip`, `values`, `valuesIn`, `where`, `without`, `wrap`, `xor`,
   * `zip`, and `zipObject`
   *
   * The wrapper methods that are **not** chainable by default are:
   * `attempt`, `camelCase`, `capitalize`, `clone`, `cloneDeep`, `deburr`,
   * `endsWith`, `escape`, `escapeRegExp`, `every`, `find`, `findIndex`, `findKey`,
   * `findLast`, `findLastIndex`, `findLastKey`, `findWhere`, `first`, `has`,
   * `identity`, `includes`, `indexOf`, `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`, `max`, `min`,
   * `noConflict`, `now`, `pad`, `padLeft`, `padRight`, `parseInt`, `pop`,
   * `random`, `reduce`, `reduceRight`, `repeat`, `result`, `runInContext`,
   * `shift`, `size`, `snakeCase`, `some`, `sortedIndex`, `sortedLastIndex`,
   * `startCase`, `startsWith`, `template`, `trim`, `trimLeft`, `trimRight`,
   * `trunc`, `unescape`, `uniqueId`, `value`, and `words`
   *
   * The wrapper method `sample` will return a wrapped value when `n` is provided,
   * otherwise an unwrapped value is returned.
   *
   * @name _
   * @constructor
   * @category Chain
   * @param {*} value The value to wrap in a `lodash` instance.
   * @returns {Object} Returns the new `lodash` wrapper instance.
   * @example
   *
   * var wrapped = _([1, 2, 3]);
   *
   * // returns an unwrapped value
   * wrapped.reduce(function(sum, n) { return sum + n; });
   * // => 6
   *
   * // returns a wrapped value
   * var squares = wrapped.map(function(n) { return n * n; });
   *
   * _.isArray(squares);
   * // => false
   *
   * _.isArray(squares.value());
   * // => true
