RingBuffer

It is a way to connect the SDF graph to an audio source or sink.

The node part is implemented in the AudioSource and AudioSink parts.

The main implementation is in RingBuffer.

To port it to new environments:

• A file RingPrivate.h must be written. It is included by RingBuffer.cpp to customize some part of the implementation
• A file managing the audio interrupts must be written an interact with the Ring buffers
• The file RingConfig.h must be provided to size the buffers
• Most of the time the Ring buffer will have only 2 buffers and will be a ping-pong buffer.
