Distutils support, reorganization and cleaning up * Removed command-line options -t and -u. * Reorganized code: o all modules are now in package upreckon; o TestCaseNotPassed and its descendants now live in a separate module exceptions; o load_problem now lives in module problem. * Commented out mentions of command-line option -c in --help. * Added a distutils-based setup.py.
