 RA.h

       I want a structure to define the code 
       which is given to an encoder or a decoder

       In the decoder, there are state variables q, f, b,
       etc.  LUMP WITH: a structure to define the decoding method, number of
       iterations, assumed noise level.

 dc    and a separate structure to define the 
       simulation parameters - true noise level, number of blocks to do.

       this str can also contain the counts of errors, and the true vector
