 /**

  * Rule for Project->Root (Top level) Elements.

  * 

  * TODO: As currently implemented it returns all top level elements in 

  * the model repository, not just those in a given project.  Since we

  * only support a single project at a time currently, these are equivalent

  * but this will need to be enhanced with additional bookkeeping in 

  * Project when we support multiple open projects - tfm.

  *

  * TODO: I changed it to get the roots from the project. It was showing

  * the profiles that were loaded but were not applied to the current project

  * - maurelio1234.
