Bruno Schmitt 5351ab4b13 xSAT is an experimental SAT Solver based on Glucose v3(see Glucose copyrights below) and ABC C version of 
MiniSat (bsat) developed by Niklas Sorensson and modified by Alan Mishchenko. It’s development has reached
sufficient maturity to be committed in ABC, but still in a beta state.

TODO:
* Read compressed CNF files.
* Study the use of floating point for variables and clauses activity.
* Better documentation.
* Improve verbose messages.
* Expose parameters for tuning.
