Is there any easy was to switch back and forth between 2-column (which in this case means: 1) setting document class to IEEEtrans with options 'journal' 2) including biographical info
and 1-column, which means: 1) setting document class options to 'journal,12pt,onecolumn,draftclsnofoot,' 2) suppressing biographical info also output should go to different file names for the 2 cases. I saw there is 'branches' feature, but can it switch the document class options?
