starting work on CompStrm again

We just had a 3-day weekend here in India and I took advantage of it to start working on CompStrm again. But please do not expect the same pace of development as before--I've got a full-time job now. ;-) Now that I've started again, I hope to do a little each day.

This weekend I dropped all references to realm and role, as well as creating a data migration path. But I figure there is no rush to release, as I have not yet added any new capabilities. Also I still lack a phone connection, so there is no way for me to connect my machine to the internet.
