Trashed most files

Listed the wrong function (a nonexistant one) in export
Debug
Debug team and conference generation

Update wintable code for NBA

makes a few changes to the wintable function so it is suitable for plotting

Passes ... parameters to 'par' and allows the record column
to have variable length.
