CASA 5.1 and fringefit
This version breaks from versions v0.4 because it requires CASA v5.1+, and it is not compatible with CASA v4.7. Other changes are:
- Support to use fringefit when it is available in CASA v5.3 (not used for the moment).
- New aoflagger strategies.
- Improved msinfo management.
- Now it is possible to execute the pipeline from a CASA session.
