Log Message:
Simplified algebra API: 'A(join=[B,C],where=d)'.  All implemented
operations are now accessible as keyword arguments to the __call__ of a
relvar.  This is more compact, clearer, and allows select/project/join and
outer joins to be expressed in a single call.  And, it eliminated a lot
of duplication between the various select/project/thetaJoin/outerJoin
method implmentations.  Also, refactored to ditch various kludges.
