That too :)  It does find the two rels (1-m and m-1) involved in the
many-many, it just doesn't hook them together into the third many-many
rel.

Having it do this automatically is on the TODO list, along with
implicit rels ( Stuff like: bar belongs_to foo (via the pk), baz
belongs_to foo (via the pk), therefore bar might_have baz and baz
might_have bar ).  In both cases, the issue is that the heuristics for
finding them might find lots and lots of inferred relationships you
didn't expect or desire really.  I don't think it will be so bad as
long as we keep things down to just two hops though.

Before the Schema::Loader's RelBuilder gains these new abilities
though, I'd first like to get it fully unhooked from the rest of
Schema::Loader so it can be used on normal schemas (and even by sqlt?)
too.
