Class PtrArrayStepper
A Stepper for stepping over the elements of a PtrArray in ascending or descending order. This is a TableStepper even though it is stepping over a PtrArray instead of a table. Should probably eventually be generalized to PrimArrays. NOTA.TYPE

Class Methodsascending: array
Note: this being a low level operation, and there being no lightweight form of immutable or lazily copied PtrArray, it is my caller's responsibility to pass me a PtrArray which will in fact not be changed during the life of this stepper. This is an unchecked an uncheckable precondition on my clients.
