There is a simple switch on the waveform in the code[0], with some code 
for each case to create the waveform. Should be no problem at all.

What I have not figured out is how to get a compact overview of the 
waveform constants. In Python this gets gr.GR_SIN_WAVE and siblings, and 
for the noise sources you have gr.GR_UNIFORM and fiends. Is there any 
way to get an collection you can scan to get all wave forms?
