		#### hash.copy( [keys] )

		Copies an [anagram](http://en.wikipedia.org/wiki/Anagram) hash table to a new hash table instance.

		``` javascript
		var copy = hash.copy();

		var list = copy.get( 'abt', true );
		// returns ['bat','tab']
		```

		To only copy specific __keys__ to a new hash table, provide a __keys__ `array`.

		``` javascript
		var copy = hash.copy( ['beep'] );

		var keys = copy.keys();
		// returns ['beep']
		```
