OFDM Modification

Hey,

I add two parameters in gnuradio-core/python/ofdm.py

 expert.add_option("","--onoff",type ="intx", default = 0,
          help="set the number of use multi_constellation decision 

[defalut=%default]")

for (i = 0 ; i<occupied-tones ; i++)
 expert.add_option("","--multi_modulation[i]",type ="string", 

default =modulation,
help=“set the number of use multi_constellation decision
[defalut=%default]”)

and run benchmark_ofdm_tx/rx.py
However, these two parameters do not work.

Are there anything incorrect? Thanks
