minor code stylistic fixes
Small tweaks to satisfy checkstyle.
Checkstyle- error for serious naming convention violations. Less noisy minor stuff (e.g. spacing).  And perform code duplicate detection, but skip the header.
Configure checkstyle and findbugs as build plugins, and setup site plugin with javadocs.  Will get Jenkins to consume this data.
