Grahm pointed out to me that we don't need both the statement id and the
model id stored with each statement.  It's not only more flexible, but
also more efficient, to store just the statement id.  For then i can
easily assign the same statement to multiple contexts and the selection
queries are much simpler than the other way around:

[context1] --rdfc:asserts--> [t1]
[context1] --rdfc:asserts--> [t2]
[context2] --rdfc:asserts--> [t1]
