Corrected arg parsing bug in execute-fits.sh.
Tidied up output in ant release script.
Altered output flag for build and execute script.
Implemented single build and test script for git bisect.
First implementation of git bisect revision testing.

This has been tested and found to work but range of test cases
hardly exhaustive.  Requires -b flag to invoke git bisect.

Closes #7 any bugs or enhancements to be added as new issues.
