/**
* Creates a 'lodash' object which wraps 'value' to enable implicit method
* chaining. 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 chaining, which must be unwrapped with '_#value' in all cases,
* 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 of at least two hundred elements and any 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', 'chain', 'chunk', 'commit',
* 'compact', 'concat', 'conforms', 'constant', 'countBy', 'create', 'curry',
