Feature Request: Player Piano Does Not Support Multiple Stereotypes

[Ross-Robertson-GTRI]

I plan on updating Player Piano to support the assignment of multiple stereotypes. Currently player piano can assign stereotypes using the following format:
"Vertex Stereotypes": { "Item1": [ { "stereotype": "Some Stereotype" } ] }

I plan to add the functionality to support list of stereotypes in the following format:
"Vertex Stereotypes": { "Item1": [ { "stereotype": ["Some Stereotype1", "Some Stereotype2", . . . , "Some StereotypeN"] } ] }

I also plan on adding some additional patterns to support different use cases I need.

1. A Composition between a Capability Configuration and Organization
2. A Composition between a Organization and Organization
3. A Association between a Organization and a System
4. A Interaction that Owns N Systems
