Deprecated some unneeded map field in V_Actor (already available in V_Node)
Removed messy business logic from V_EdgeList
Added comments to V_GenericNode
Removed the need for the Edge List to store the actual node object endpoints, and instead just use the ids.
Fixed potential NPE coming from federated graph service.
Updated comments about addData
Fixed some NPE potential pitfalls
Changed implementation to use TreeSet so that the values are properly sorted.
Need to add ability to color and style the edges, and to style the node shapes.
Made the IDProperty class comparable, so we can have sorted collections.
family is now starting to be called nodetype
Removed some cruft from Vande.  The XML graph generation service should no longer be used in Graphene, and also the xml annotations have stopped working for some reason, so I've commented them out for now.  All graph rest services should be using the cytoscape format for the initial call and the expansion/pivot
added the option for a cytoscape specific option of having parent groupings.  Sometimes it looks good, but it doesn't layout or inherit it's childrens edges.
Changed to version 1.1
Added size getter to edge list.
Added method to allow node attribute inheritance
Merge branch '4.1'
