Examples of running tester.

1. Use meld to present differences between /opt/esp-r/bin/bps and /opt/esp-r_test/bin/bps
   and keep result in folder 'results_output'.

./tester.pl -v --no_h3k --diff_data --diff_tool meld --databases /opt/esp-r/ /opt/esp-r_test/bin/bps /opt/esp-r/bin/bps --ref_loc /opt/esp-r_test/bin --test_loc /opt/esp-r/bin --save_results

2. Do not invoke meld and run only the test models within 'ccht_benchmark'.
./tester.pl -v --no_h3k --databases /opt/esp-r/ /opt/esp-r_test/bin/bps /opt/esp-r/bin/bps --ref_loc /opt/esp-r_test/bin --test_loc /opt/esp-r/bin --path ../test_suite/ccht_benchmark
