Dan Liew 7cc12bf59f Update information in `README.md` on Python bindings. Since 
e9ea687bb9 they aren't on by default.
Now ``--python`` needs to passed.

Also give better documentation on how install the Python bindings
outside the install prefix.

Nikolaj Bjorner 131f9e2247 change queries to take function names instead of arbitrary predicates. This allows to bypass issues with having arbitrary query expressions compiled in arbitrary ways to auxiliary predicates where names of bound variables are reshuffled.
