Introducing synd

[Timo Westkämper]

I'd like to announce that I am working on synd, a partial port of 
the STK library (https://ccrma.stanford.edu/software/stk/) to D.

synd provides basic building blocks for synth design such as 
envelopes, oscillators, delays and a few effects.

I do this while waiting for Linux shared library support to 
become available in D;)
