Mavenized Project

Reworked project into maven layout giving it 'com.codebox' group.  Using
personal banner for site page as I couldn't find a cool pick to go with
codebox.  Feel free to change all that.  Part of the reason I'm looking
to do this was to get this unit tested as well, determine code coverage,
and ultimately build out tests for toString, hashcode, equals, etc.

One note:  I used lombok for the SampleBean.java.  If you want to use as
well, it requires integration into IDE.  See http://projectlombok.org/
for details.  Otherwise, simply have eclipse or favorite IDE generate
the getters/setters.
