Adding copyInto and toVector methods to collections.
* Added generic copyInto method for collections. For any collection with a CanBuildFrom, can convert a generic collection into it using the builder.
* Added specifici toVector method for collections. This is more efficient than copyInto if the collection is a Vector.
