Merge datatype shared selectors/sygus comp 2017 branch. Modify the datatypes decision procedure to share selectors of the same type across multiple constructors. Major rewrite of the SyGuS solver. Adds several new strategies for I/O example problems (PBE) and invariant synthesis. Major simplifications to sygus parsing and synthesis conjecture representation. Do not support check-synth in portfolio. Add sygus regressions.
