Add C++ functions for set operations per stackoverflow post, set relevancy = 2 for quantified maxsmt per example from Aaron Gember, fix conversion of default weights based on bug report from Patrick Trentin on maxsat. Annotating soft constraints with weight=0 caused the weight to be adjusted to 1 and therefore produce wrong results
