Model no longer adds subterms of quantifiers to equality engine, this fixed bug 492 and resolves previous issue for bug 486.\n Multiple improvements for E-matching: do not choose multi-triggers if single triggers exist, only create multi-triggers that contain all variables, consider multiple terms per equivalence class but only add one instantiation per round per (trigger,term) pair.\nImprovements for strong solver: make use of sort inference information when choosing splits, check for cliques eagerly when disequalities are asserted.
