Title: updated with Sven's work from March

I think I'll need to redo this again after you incorporate the name change. The only code changes I made are the addition of a Stack class (subclass of OrderedCollection) with these methods:

pop
^self removeFirst

push: anObject
self addFirst: anObject
^anObject

top
^self first

After that 104 of 109 tests pass. The failures are from Floats that are very similar not being equal. There is one error I'm not sure about.
