Beta Version 0.4.0 Committed to SVN

Latest SVN is updated to version 0.4.0 with new API changes. The older versions of 0.3.x will be maintained as a new branch, so those who still use 0.3.x do not worry.

The code in SVN is considered beta until enough tests and user feedback have been made. A BETA release will be made once a compilation of changes and documentation is completed.
