/*! \class Generator
\brief STK abstract unit generator parent class.
This class provides limited common functionality for STK unit
generator sample-source subclasses. It is general enough to
support both monophonic and polyphonic output classes.

The \c channel argument plus the number of output channels must
be less than the number of channels in the StkFrames argument (the
first channel is specified by 0). However, range checking is only
performed if _STK_DEBUG_ is defined during compilation, in which
case an out-of-range value will trigger an StkError exception.
