e58cfe1c8f Added function to print unsat core in dimacs format 
Thgis is meant to be used for debugging and/or benchmarking purposes.
For instance, when using msat in an application, all unsat cores can
be output this way to different files so that the results can be checked
and easily reproduced in case of errors.
