Returning output instead of writing to disk

It would be useful if TICC could be used without generating extra files and directories. The following lines can be removed without any apparent change in functionality:

TICC/TICC_solver.py

Lines 62 to 68 in c8296df

    
           str_NULL = prefix_string + "lam_sparse=" + str(lam_sparse) + "maxClusters=" +str(num_clusters+1)+"/" 
        
           if not os.path.exists(os.path.dirname(str_NULL)): 
        
               try: 
        
                   os.makedirs(os.path.dirname(str_NULL)) 
        
               except OSError as exc: # Guard against race condition of path already existing 
        
                   if exc.errno != errno.EEXIST: 
        
                       raise

Results are also written into results text-files which is not always what a user of this code wants (e.g. the second argument to the RunTicc). Maybe just supporting output_filename=None would be useful.
