55126692c9 spacer: counterexample to pushing (ctp) 
Enable using fixedpoint.spacer.ctp=true

For each lemma L currently at level k, keep a model M that justifies
why L cannot be pushed to (k+1). L is not pushed while the model M
remains valid.

3c7165780c Extend spacer with callback events 
Callback events allow the client of spacer to
get events during exection. The events include
new lemmas and unfolding.

23a8e59493 Initial commit of QGen 
Controlled by fixedpoint.spacer.use_quanti_generalizer

measure cumulative time, number of invocations, and number of failed
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.
