(coll) Add E[] toArray(Class<T>) so that an array instance is not required

A DESCRIPTION OF THE REQUEST :
* Add E[] toArray(Class<T>) so that an array instance (like (Foo[])toArray(new Foo[0]) is not required). Get rid of E[] toArray(E[]).

Why does one need to have an array instance for toArray (??). I see this as a deficiency in obtaining the class representation of an int array. Almost _every_ time i've seen toArray being used or being used by myself there has been a zero length array. E[] toArray(Class<E> classType) should be sufficent.
