           Description: Describe your changes here...

Replaced the call to drive the parser to the new interface which
requires the sub-table and the required main-table columns to be
constructed outside.  This allows use of the parsers for tables
of the generic type MSSelectableTable.

Modifed the older interface in MSAntennGram.cc to also work as before.
I.e., for MS, the old and the new interfaces will both work.

Reverted tMSAntennaGram3.cc to it's original code.

           Description: as above, done at Ger's request. I didn't know about ArrayPositionIterator when I implemented IPosition::next()

What Interface Changed: 
         Test Programs: test_concat.py, manual tests
  Put in Release Notes: Yes
             Module(s): ms
           Description: concatenation will now proceed no matter whether column
                        FOCUS_LENGTH exists in the FEED table in both MSs or not.
                        If it exists in the first MS, it will keep the 
                        FOCUS_LENGTH column in the output, otherwise not.
			Clear warning messages are issued if the column is present
			in one MS but not in the other.

  Put in Release Notes: No
             Module(s): 
           Description: 

Modified the column objects to support effectively collapse the class
hierarchy.  When you create a previously read/write object you have
the chance at construction time to make it readonly.  When made
readonly, a put operation will generate an exception.  This change
makes it easier to have these objects as instance members of other
classes, especially the VisibilityIterator, which can be behave as
either RO or RW.
