## DESCRIPTION

     Plugin for seqIo and videoIO to allow writing of seq files.

     The following is a list of commands available (swp=seqWriterPlugin):
      h=swp('open',h,fName,info) % Open a seq file for writing (h ignored).
      h=swp('close',h)           % Close seq file (output h is -1).
      swp('addframe',h,I,[ts])   % Writes video frame (and timestamp).
      swp('addframeb',h,I,[ts])  % Writes video frame with no encoding.
      info = swp('getinfo',h)    % Return struct with info about video.

     The following params must be specified in struct 'info' upon opening:
      width          - frame width
      height         - frame height
      fps            - frames per second
