Anti-aliased oscillators #170

For now at least want to do:

Not sure which technique will be the best fit for Tonic, so some experimentation is in order.

In the future it would be nice to have a more all-purpose anti-aliased lookup oscillator.

It sounds like minBLEP is a popular and fairly efficient approach, when using a table-lookup optimization.

There is plenty of example code out there (and it's public domain, so we can easily adapt it for Tonic and not worry about license conflicts):

I'm planning on creating a DSPUtils file that abstracts out some of the DFT, cepstrum, etc for use across generators (and potentially with platform-specific optimizations, e.g. vDSP).
