Kovid,

Since I had to reverse engineer Custom Columns in order to understand what needed to be done to add a new Custom Column datatype, I documented it in the attached zip file. It includes the Calibre 2.61.0 .py files that had any changes, plus some .png files proving that it works properly.

I thought perhaps it might be useful to someone trying to do the same thing in the future.
