++++++++++++++++++
- New and improved command-line interface. Legacy CLI is not supported. Sorry. See the documentation or execute ``sidewalk --help`` for more information. The CLI should not change in the future.
- Greatly improved error handling and logging; added ``traceback`` output for unhandled exceptions, i.e. exceptions caused by activity processors or bad refences to activity processors.
- Moved locations of ``bin/`` and the core libs into ``sidewalk/bin`` and ``sidewalk/core``, respectively.
- Updated documentation and README.
