History:
2008-07-30: Created to refactor Build Atoms command (currently called
BuildAtoms_Command).
TODO:
- Classes created to refactor BuildAtoms_Command (rather 'BuildChunks' command)
to be revised further.
- document
- REVIEW: _reusePropMgr_of_parentCommand -- this is an experimental method
that will fit in the NEW command API (2008-07-30) . to be revised/ renamed.
e.g. command_reuse_PM etc.
- Update methods (e.g. self.propMgr.updateMessage() need to be called
by a central method such as command_update_* or PM._update_UI_*.
