Title: Add support for Variable subtrees

_Note: This assumes a subtree with variable="true" attribute. precondition[147-148] will have to be updated when the MAT staging server updates to support variables._
### Notes ###
- pass @variable from within data_criteria.to_model()
- added missing comment to precondition.handle_satisfies()
- added precondition.handle_precondition()
- create grouping data criteria for the variable
- construct source data criteria from entry/data criteria
- added test_with_variable and associated fixture data
