Modified indeces to be more consistent with the implementation in the Aho text
Finished test procedure and renamed it because it should be compatible with both array and pointer list implementations
Started writing pointer implementation, specified position type to be just for array implementation (so I can have a type for the list implementation later)
Implemented pointer list.  Turns out I can't do a type templated typedef (makes sense), so I need to write a slightly modified test for the pointer implementation
Finished pointer test, moved test procedures into a single main file
Implemented array and pointer stacks, and added tests
Put each data structure and it's test in its own directory with its own makefile per assignment instructions
Added missing tabs in makefiles
Final commit before submission.  Wrote timing procedure ot time all implementations for different data sizes
