2017-01-11	Fix for when variables are (partially) bound in multiple ways, add ↵	ajreynol
	regression. Improve printing for bound int module. Track when relations are enabled in sets, set incomplete if card+rels are both enabled since model construction is not guaranteed to succeed.

	Fix dependency tracing for fewerPreprocessingHoles
2016-12-29	Changing a set of TNodes to a set of Nodes in the BV inequality solver. The ↵	Tim King
	ref count of the TNodes in the set can become 0. Set operations containing garbage collected TNodes could then fail.

2016-12-16	Fix dependency tracing for fewerPreprocessingHoles	Andres Notzli
	Previously, dependency tracing in `ite_removal.cpp` was only done with the `unsatCores` option but `fewerPreprocessingHoles` requires dependencies, too. This lead to errors during proof construction when `fewerPreprocessingHoles` was active. This commit fixes the condition and includes a test case that previously failed. Additionally, it fixes a similar issue in the theory engine. NOTE: this commit might not fix all instances of this problem. `smt_engine.cpp` turns certain flags off with `unsatCores`. Compatibility between those flags and `fewerPreprocessingHoles` needs to be checked separately.
2016-12-14	Switch from SMT-LIB v2.0 to v2.5 for smt2 files	Andres Notzli
	As mentioned in bug 741, CVC4 was parsing `.smt2` files using the SMT-LIB v2.0 standard by default. This commit switches to v2.5.
2016-12-14	Made tear-down-incremental more like it used to be: when tear-down value	Clark Barrett
	is 1, it does not automatically enable incremental mode.
2016-12-11	Merge branch 'master' into fix_order	Clark Barrett

2016-12-11	Merge pull request #116 from 4tXJ7f/fix_mult	Clark Barrett
	Fix (inactive) `MultSlice` rewrite
2016-12-09	Fixing a use after free bug in Polynomial::denominatorLCM.	Tim King

2016-12-08	Fix initialization order	Andres Notzli
	This commit addresses the following warning: ``` warning: field 'd_negOne' will be initialized after field 'd_pivots' [-Wreorder] ```
2016-12-08	Fix (inactive) `MultSlice` rewrite	Andres Notzli
	The `MultSlice` rewrite was previously accepting multiplications of three and more variables even though it was designed for multiplications of two variables only. Fortunately, the rewrite was not actively used in the bitvector solver. This commit strengthens the condition in `applies()` and adds a unit test that checks that x * y * z and x * y do not get rewritten to the same term.
2016-12-07	Add sets regression, fixes bug 754. Minor fix to regexp in strings.	ajreynol

2016-12-07	Added cardinality to cvc language, fixes bug 753. Throw logic exception when ↵	ajreynol

	It was turned off for unsatCores, and fewerPreprocessingHoles using the same infrastructure.
2016-12-07	Refactoring, generalization of bounded inference module. Simplification of ↵	ajreynol
	rep set iterator. Disable quantifiers dynamic splitting for variables that are inferred bounded. Minor changes to fmc mbqi. Add regressions.
