/**
Data collection system that uses the ninelocks ring buffer and record ring buffer library as part of a data collection system
This is based on very old early 1990s code from another project. Its been tweaked to allow use of the mbed

This code expect you to derive your own data collection function inheritaed from this class and implement your own functions ofr
