Hi all,

In one of my projects I wanted to use copy on write list. I slightly improved this implementation and thought it would be nice to add it to commons collections, as I couldn't find something like this.

Implementation details:
- the original list is wrapped with CopyOnWriteList,
- on modifications the original list is copied and copy is used instead,
- for iterators before modification, the cursor index is used and then new iterator is set on on required position (this can't be done for abstract collections)

I hope there is no flaw in my designs,

Best regards, 
Radek Smogura
