algorithms to conform to it, uniformly. This will unfortunately break third-party code that were using these algorithms. * src/tgbaalgos/emptiness.cc, src/tgbaalgos/emptiness.hh: New files. * src/tgbaalgos/Makefile.am: New files. * src/tgbaalgos/magic.cc, src/tgbaalgos/magic.hh: Adjust to conform to the new emptiness-check interface. * src/tgbaalgos/gtec/ce.cc, src/tgbaalgos/gtec/ce.hh, src/tgbaalgos/gtec/gtec.cc, src/tgbaalgos/gtec/gtec.hh, src/tgbaalgos/gtec/status.cc, src/tgbaalgos/gtec/status.hh: Likewise. The classes have been renamed are as following emptiness_check -> couvreur99_check emptiness_check_shy -> couvreur99_check_shy counter_example -> couvreur99_check_result * src/tgbatest/ltl2tgba.cc, iface/gspn/ltlgspn.cc, iface/gspn/ssp.hh, iface/gspn/ssp.cc: Adjust to renaming and new interface.
