Detailed Description
The SampleRaster is a small utility processor that quantisizes timestamps of midi data to a specific step size.
If a midi message has the timestamp '15', and the step size is 4, the new timestamp will be '12'.
This allows assumptions about buffersizes for later calculations (which can be useful for eg. SIMD acceleration).
Constructor & Destructor Documentation

Creates a SampleRaster.
The initial step size is 4.
Member Function Documentation

Applies the raster to the timestamp.
Implements MidiProcessor.

This sets the quantisation size.
It is supposed to be a power of two and smaller than the buffer size.
