CTL checker

[mondokm]

• Symbolic CTL model checking over the MDD backend via MddCtlChecker (EX, EU, EG, plus derived CTL ops).
• Constrained-saturation support for EU through AndNextStateDescriptor, this means we have two different algorithms for EU
• New common/ctl module with ANTLR grammar + parser
