* Connect the plumbing so that BV proofs are enabled when using
CryptoMiniSat
* Also fixed a bug in CNF-proof generation
* Specifically, CNF proofs broke when proving tautological clauses.
Now they don't.

* ErProof class with LFSC output
* Created a TraceCheckProof class
* parsable from text
* Created an ErProof class
* constructible from a TraceCheckProof
* writable as LFSC
* A bunch of unit tests
* Reponded to Mathias's first set of comments.
Credits to Mathias for many of the fixes!
* Responed to Andres's first set, fixed tests
I accidentally deleted a "!" last time, causing stuff to fail.
* Use Configuration::isAssertionBuild
* Clarified comment
* Responded to Andres's 2nd review
* Gaurding against a memory error.
* Renaming a file.
* Aggressively unlinking temporary files.

* LFSC ouput & unit test
* Renamed lrat unit test file
* s/DRAT/LRAT/
Thanks Andres!

* Addressed Andres' comments
1. Extracted a filter whitespace function.
2. Added @param annotations.
* Addressing Yoni's comments
Tweaked the test method name for LRAT output as LFSC
Added assertions for verifying that clause index lists are sorted during
LFSC LRAT output.

* Print LFSC proofs of CNF formulas
* Unit Test for clause printing
* Added SAT input proof printing unit test
* Fixed cnf_holds reference. Proofs of CMap_holds
There were references to clauses_hold, which should have been references
to cnf_holds.
Also added a function for printing a value of type CMap_holds, and a
test for this function.

* LFSC drat output
* Addressed Mathias' review
Addressing Mathias' review with the following changes:
* Added a few blank lines
* Added a unit test for LRAT output as LFSC
|
|
* Copied old DRAT data-structure files.
Next step: clean up the code, and adapt them to our current usage plans.
* Polished the DRAT class.
Notably, removed the idea of lazy-parsing, this is now just a DRAT
wrapper class.
More explicit about whether methods handle binary or text.
Better constructor patterns
* Added implementation of textual DRAT output
* reordered the DratInstruction structure.
* removed the public modifier from the above struct
* removed the operator << implementation for DratInstruction
* use emplace_back
* Addressing Yoni's first review
* Extracted "write literal in DIMACS format" idea as a function
* Replaced some spurious Debug streams with `os`. (they were left over
from an earlier refactor)
* Improved some documentation
* Removed aside about std::string
* Addressed Mathias' comments
Specifically
* SCREAMING_SNAKE_CASED enum variants.
* Extracted some common logic from two branches of a conditional.
* Cleaned out some undefined behavior from bit manipulation.
* Unit tests for binary DRAT parsing
* Added text output test
* s/white/black/ derp
