SMT calls
Relaxing equality in a pattern: if a variable equals a numeral, relax with GE
pob::get_skolems() returns all skolems that might appear in the pob.
New skolems must be added above the largest index in that map,
even if they are not used in the pob itself.
pattern generalization should be done before the pattern is skolemized and
added into the new cube.
