valueInterval property
Set a context track to play periodically every valueInterval
units of a data property valueProp while the sonification is
playing.
For example, setting valueProp to x and valueInterval to 5
will play the context track for every 5th X value.
The context audio events will be mapped to time according to the prop value relative to the min/max values for that prop.
