-       * Creates a `lodash` object which wraps `value` to enable implicit method

-       * 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.

+	     * 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.
+	     *

+	     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
