PA2 Finally Shows Progress

PA2 is still not a comfortable area for me, but I can proudly say that after two days of work, the first set of tests is passing.  The tests defined in memory_test.cpp are out of the way...though I know full well that the destroyHeap method has a huge leak because I can't figure out how to delete a heap without throwing access violations.  But that's a problem for another day.

First set of tests down!
