The Groups Registry backing the Grouper API is necessarily relational. 
Sites might load group related info into the Registry or provision it 
from there to stores of whatever sort.

Grouper 0.5 ships with 2 subjectTypes: 'person' and 'group'. Sites can 
extend the set of subjectTypes. The subject interface is an abstraction 
for dealing with subjects of different subjectTypes. For each 
subjectType a declared adapterClass implements the interface, allowing 
sites to provide site-specific resolution services for 'person' and 
other subjectTypes. The Grouper API includes an adapterClass for the 
'group' subjectType, and for its sake pagination will be tied to the 
relational backend somehow.
