Clean-up Graph Refactor

[minoumao]

A general list of features in need of cleaning up from GAMMS 2.0
Note: (?) means uncertainty if change is needed

Inital Clean-Up List:

• Update custom drawers to use data instead of artist context
• Update draw circle command to be compatible with older calls and allow radius overwrites (?)
  • Currently, radius is set via artist.data['radius'] and checked live.
• Enable backwards compatibility for data with GAMMS 1.0. Specifically allow dictionaries to be usable.
• Clean up NO_VIS and ensure all related human input operations do not block.
  • Human input in NO_VIS will just return the existing position. No allowance for human_input to be called in NO_VIS(?)
• Clean up waiting_for_human_input() and related calls in NO_VIS
• Create an internal graph overlay in place of the graph overlay drawing.
• Begin enforcing proper function calls and requiring all out-of-reference memory writes to operate through function calls.
  • For the immediate future, tag write functions will be used in comments.
• _redraw_graph_artists() does not respect layer authority

This list will be updated over time.
