binica() - Run stand-alone binary version of runica() from the
          Matlab command line. Saves time (12x) and memory (4x). 
          If given a data filename, data need not be read into Matlab,
          allowing processing of larger data sets.
 Usage:
         >> [wts,sph] = binica(datavar, [ica keywords, args]);
  Else   >> [wts,sph] = binica('datafile',chans,frames,[ica_keys,args]);

 Inputs:
         datavar = (chans,times) data matrix 
         datafile = quoted 'filename' of float data file

 Allowed ica_keys and default args:

         extended       0   [default: don't look for subGaussian components]
         pca            0   [default: don't reduce dimension]
         blocksize      0   [default: use heuristic blocksize]
