Removing FindBugs Excludes, since all they did was remove tests from the examples modules. Instead I removed the unnecessary reporting from examples. ...

Also, I've removed the umlgraph from the javadoc. It's useful, but it causes the build to complain loudly on windows machines.

Adding findbugs exclude rules to other projects.

Making checks for examples far less restrictive than the core library. Snippets don't always need to conform to SOLID principles.

Killing more CheckStyle and a Couple PMD complaints.

Making CheckStyle more permissive of things the Piccolo2D code base doesn't agree with.

Issue 29 ; Tweaked checkstyle configuration and ran eclipse formatter on the java source in examples. Reduced checkstyle errors from 5877 to 1352. Note this commit contains formatting-related changes only, no code changes.

Issue 28; re-adding checkstyle plugin configuration to core, extras, and examples poms, adding sun_checks.xml to src/build/conf in each to enable check configuration
