-Added cleaner output of connectors
-Moved around one of the if statements to a better spot in connectorsDFS
-Created a prev array. I'm not sure, but I think that having 1
constantly changing value for prev might cause some problems (like when
backtracking and visiting multiple nodes)
I may be wrong, so I left the prevV stuff where it was but just
commented it out
-Implemented a potential condition to correctly identify the root of a
dfs as a connector (I think)
-A few other little things here or there
