[chuck-users] stupid n00bie question: Part III

[AlgoMantra]

Thanks Joerg.

although to be honest, I wasn't looking for the theoretical solution
but what kind of Chuck code objects to use for this. My Chuck
learning curve seems way slower than Python/PD, I don't know why.
I think it's the lack of explanatory notes in examples, or some kind
of proper tutorial.
