Description: Describe your changes here...

First version of calibration classes for sky calibration (STCalSkyPSAlma)
and Tsys calibration (STCalTsys), which are derived from base class
(STCalibration).

The caltable classes, STCalSky and STCalTsys, are renamed as STCalSkyTable
and STCalTsysTable, respectively.
