Description:

I am an ordered collection which automatically resizes if elements
are added beyond the size. 
I.e. if #at:put: is sent for indexes > the current size, the receiver grows to
the required index and missing fields are implicitly filled with nils.
Queries for non-existing elements are anwered with nil.
