Better handle template names/refs

[Michael Albert]

It is likely that if two nodes (A and B) of the same name existed and another node (C) was constructed with the names of A and B as the template, the ambiguity would result in one of the nodes appearing as the template (possible B) depending on the map assignment in the ParsedTopology object. Construct a more graceful approach for resolving this ambiguity.

In Scope:

• resolve ambiguity when using another node with a shared name as a template
• retain ability for multiple nodes to share a name
