[chuck-users] chuck manual errata

[Perry R Cook]

I think we should credit Tim Stilson and others
for the actual algorithm, yes?  Band-limited
impulse generation dates back to early Bell Labs,
and probably Gauss.  Steiglitz, Moorer, and others
looked at efficient "sum of cosines" algorithms
back in the 1970's.  Tim with Julius brought a
number of hacks to help this, and enhanced it
for sawtooth and other waveforms.  Anyway, just
piping in on a little bit of history.
