% REMOVEKEYS removes keys from a PLIST.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% DESCRIPTION: Removes from the first input PLIST the keys which are
%              specified as the second in a cell-array.
%              This method will keep the oder of the keys inside the PLIST.
%
% CALL:        pl = removeKeys(pl, 'key');
%              pl = removeKeys(pl, {keys});
%              pl = removeKeys(pl, plist('remove', {keys}));
