[LDCad] Make 572c01 flexible

[Magnus Forsberg]

Or do I need to make 572b obsolete, and then place the content of 572e in my new flex_section file?

Help me think here.

I think we should obsolete the old files 572a, 572b and 572c. They have been official and can't be changed, and 572b is not good to use in the template.
So, should I obsolete all three, or only b?  The other 2 could be Move to-files.

572c01 and c02 could be Moved to-files, to the new partnumbers.
