Okay, thank you ... new issue....
I am using a labeled_graph, and if I assign a vertex property and then try
to get that node again to check the value (like so):
Vertex rootVert = patentGraph[rootName];
rootVert.vertType = "Root";
rootVert = patentGraph[rootName];
At the end rootVert.vertType is no longer "Root".  Am I getting some sort of
const reference such that my assignment is getting dropped on the floor?
If Vertex is your vertex property type, you are getting a copy and so your 
updates are being dropped.  Declaring rootVert as a Vertex& might fix your 
issue.
