Raymond Mui:
Most of Makefile
Initial structure of most files, including most of header files
freemem.c
print_heap.c

David Rennick:
test and dist targets in Makefile
getmem.c 
get_mem_stats.c

The initial concepts, and methods of operation, were planned out collaboratively.
The implementation was divided between members and testing was done by each member as needed.

Malloc is used to allocate new 4096 byte blocks as needed.

The header of each block consists two uintptr_t sized sections.
The first stores the size of the data section of the block.
The second stores a pointer to the data section of the next block
The remainder of the block is for the user's data.

The list of free data functions as a singly linked list using the "next" section of the blocks
to point to the next element of the list.

Blocks are referred to using a pointer to their data sections, and all other values are
calculated using get functions.

The wikipedia page on dynamic memory allocation was used to get a basic understanding of structure
and terminollogy for the project.
