- removed the 'thirdparty' directory (now the 'gridworks' script will download and install needed tools if they are not present in the system already)

Browse Source 
- added 'findbugs' command that uses the findbugs static analyzer to look for problems in the code
- fixed a bunch of issues that findbugs found (a few methods would go a little faster, and a few NPE will be avoided... nothing major but good to have)
