Connections: From FileIO to DataManager, Graph

The FileIO will work by using serialization techniques in the Graph subset
of data (Object, Connections) by using the << and >> operators to store each
sub component into a retrievable format.  The fileIO will traverse through
the data structures of the Graph, outputting these objects to file, and then
it will create new objects from a stream and insert them into the Graph upon
a read command.
