What would be required to generate and export a .webgmexm of a software model based on a deployment

[AWatk]

I.E. Generate a software model tree that is a subset of the current project's software model that contains only the relevant components to the deployment at hand.

Example

Project Software Model: 
  Library-1
  Library-2
  Package A
    Component A.1
      Uses Library-1
    Component A.2
    Component A.3
  Package B
    Component B.1
    Component B.2
      Uses Library-2

Deployment Model:
  Container
    Node 1
      Component A.1
    Node 2
      Component A.2
       Component B.1

.webgmexm Software Model:
  Library-1
  Package A
    Component A.1
    Component A.2
  Package B
    Component B.1

realistically we would want the plugin to act on an Experiment so that it will find the deployment, system model, and from there the relevant components that need to be exported.

Looks like we can use exportModelsToFile from webgme-engine/serialization.js
