* FIXME JBB: Should work out the difference between DATA_APPLIED AND APPLIED events
* current DATA_APPLIED occurs first and fNewDescription is modified. Need to clearly define
* the project description state transitions
* The ProjectDescription lifecycle looks like:
* <ul>
* <li>
* - {@link #LOADED} - configuration is loaded and read-only
* <li>
* - {@link #COPY_CREATED} - Indicates new writable description has been created from
* the read-only description backing store
* <li>
* - {@link #ABOUT_TO_APPLY} - First event in the setProjectDescription flow. New description
* writable, old description represents the cache
* <li>
* - {@link #DATA_APPLIED} - Event indicating that configuration data has been applied by the build system
* <li>
* - {@link #APPLIED} - setProjectDescription finished, newDescription is read-only
* </ul>
