Name: Collections-ul.695
Ancestors: Collections-topa.694

Heap revamp #1:

class side:
- Heaps can be created on an existing array with #on: #on:size: and #on:size:sortBlock:
- #withAll: and #withAll:sortBlock: avoid creating an extra copy if the argument is already an Array

instance side:
- imported and improved #= from Pharo
- #growTo: won't raise an error when newSize is less than array size (e.g. during compaction)
- #sortBlock: restores the heap invariant on its own
- improved #select:, #collect, #at:, #removeAt:, #add:
- added #sort and #compact; compatible with other collections
- #capacity returns the real capacity
- inlined #sorts:before: and #indexUpdateBlock: for performance
- improved performance and legibility of the heap operations #upHeap: #downHeap: and #downHeapSingle:
- added #isValidHeap
- added some comments
