Removed old class TA2Calibration

Old calibration class TA2Calibration is removed. This class is outdated
and replaced by a class TA2CaLib (already included).
TA2CaLib now using only standard analysis classes

TA2CaLib is now calling only standard classes (currently TA2Taps
and TA2CentralApparatus) instead of the My* classes which, in most
cases, were just bare-bones versions of old apparatus classes.
This change provides two benefits:
1. the same classes are now used for analysis AND calibration
2. these special case classes can be removed
Removing outdated My*** classes originally in place for CaLib

Still moving towards a concise Acqu set of analysis classes...
all classes designed only for running with CaLib have been
replaced by the standard classes. The old classes are now
un-used and therefore have been removed. Preliminary testing
shows no odd behaviour.
