Changes

Specify, for an individual column in a columnset, on what line you want its contents to start. Say that a column is setup with {{cmd|setupcolumnsetlines}} to have 40 lines, and with {{cmd|setupcolumnsetstart}} to start on line 15, then the column will have lines 1-14 empty, and text in lines 15-40; any text beyond that will end up in the next column.
