Title: Ensure Extend is implemented and renamed Extendable to Extend

Ensured that Extend & FromIterator are implemented for the libcollection.

Removed the fact that FromIterator had to be implemented in order to implement Extend, as it did not make sense for LruCache (it needs to be given a size and there are no Default for LruCache).

Changed the name from Extend to Extendable.
