Connections: From PassiveUI to Data Manager, Event, and Graph

The passive UI needs to be able to access the data manager in order to get to
the graph data structure and to pass events to the system.  It will be
responsible for constantly updating the information stored in the Data
Manager as dictated by the user input.  It will then need to be able to
get at the Graph structure through the Data Manager in order to display it
on the screen.  In order to display the information, it will have to iterate
through lists of connections and Object objects (accessed through the Graph)
and use the data stored inside them by the PassiveUI to figure out their
onscreen location.
