Removed Debugging Statements/Methods

Removed all the unnecessary debugging statements and methods,
re-implemented the text interface.

The next step is to now begin writing the Map class! However, NOTE: To
better follow correct terminology, Map will be called Graph. Everywhere
I've been using the word/term "Map" will now be replaced with "Graph".
They mean the same.

Side note: I'm just happy my getIndex method on EdgeLinkedList seems to
work 100% the time everything else is working. Pretty proud of myself
for that one.
