This is a port of the clojure collection classes to be more approachable from a pure java project.

• New PersistentList, TransientList

• PersistentTreeList - Immutable List implementation with structural sharing
• TransientTreeList - Mutable partner to PersistentTreeList

TransientTreeList isn't a complete list implementation:

• only add and remove are implemented
• clear()/subList().clear() haven't been implemented
• iterator().remove()
• It doesn't fail fast with ConcurrentModificationException's althrough it may not be nessary as it is only editable by a single thread
