experts: Multiple minor fixes/enhancements

- Fixed segfault issue for graph modification errors
- Demangled node type names and added quotes to "dot" labels to allow fully qualified C++ names
- add_prop_node functions initialize the property objects in the tree in addition to data nodes
- Passed in resolve mutex to desired data node correctly
- Added == and != operators to data accessors
