RMSEA() improve to handle models that lack ref models #155

Closed tbates closed 3 years ago

tbates commented 3 years ago

RMSEA() currently assumes the model already has refModels, which is not the case for OpenMx raw data models. Wrap in umx's support for building these so RMSEA() is not NA for raw models

Consider returning the model with these included to save time for subsequent runs.

needs more work to support:

[x] turn RMSEA object into a class
[x] create print object
[x] check for existence of saturated fit and compute refmodels if NULL
