Added BitMatrix object and AdjMatrix and PermMatrix classes.
Fixed BitMatrix; need to figure out how PermMatrix and AdjMatrix are actually inherited.
In the middle of simplifying Graph class.
In the middle of implementing HashTable and getting rid of Tree.
Making Table.
Updated README and TODO.
Graph objects are now properly allocated using BitMatrix.
Children are now saved as Node[] instead of LinkedLists.
Making makeTable() method.
Deleted some old classes.
Started adding JUnit tests.
Started writing TableTest.
Fixed implementation misunderstanding.
Finished tests for TableList and Table classes.
Made makeTable() method.
Thinking of making a Map object using the Table class...
Finished writing all of areIsomorphic. Now to debug.
Thought of how to generalize to nonconnected graphs.
Improved Matrix tests.
Generalized to possibly disconnected graphs.
