PSCUBE - PostScript image plot of a data CUBE                

 pscube n1= n2= n3= [optional parameters] <binaryfile >postscriptfile  
    or                                                     
 pscube n1= n2= n3= front= side= top= [optional parameters] >postscriptfile

 Data formats supported:                                   
      1. Entire cube read from stdin (n1*n2*n3 floats) [default format]
      2. Faces read from stdin (n1*n2 floats for front, followed by n1*n3
         floats for side, and n2*n3 floats for top) [specify faces=1]  
      3. Faces read from separate data files [specify filenames] 

 Required Parameters:                                      
 n1                     number of samples in 1st (fastest) dimension   
 n2                     number of samples in 2nd dimension       
 n3                     number of samples in 3rd (slowest) dimension
