Add support for groups or 'teams of teams'

[DinisCruz]

This would allow the consolidation of teams data and results

Handles the case where a particular project will have more than one sub-project which requires a Maturity Model in its own right

Also handles the case of submodules used by a particular project (since there is an argument that they should affect the master one)

One idea will be to have a global score for the entire project (based on the consolidate number of Yes and No values), which can then be feed into another projects (this would actually scale quite nicely since it would allow a chained of project's dashboards, each one feeding the one above, all the way to a global CISO dashboard)
