/* CHANGELOG
1.0.2 (1/15/2014)
- changed license to LGPL
- updated style
- added a test mode, so I can work on visual changes more easily
- modified the main function to return the created button
1.0.1 (12/13/2013)
- slight tweak for more flexible styles
buttons now have a special class which you can modify.
you can even put buttons outside of the container with
that class, and they will have that style applied
1.0.0 (12/13/2013)
- created
