Provides mutable access to a value.

Mutable is used as a generic interface to the implementations in this package.

A typical use case would be to enable a primitive or string to be passed to a method and allow that method to effectively change the value of the primitive/string. Another use case is to store a frequently changing primitive in a collection (for example a total in a map) without needing to create new Integer/Long wrapper objects.
