Example code to use the driver for reading waveform

The example code shows how to read a waveform using the drivers. The code enables reading of high precision waveform as well.

An example code that enables reading high precision code using the drivers is provided.
Adding set(groupObj, 'Precision', 'int16') lets one read the 12 bit waveform. You can remove this line if you are using it with 8 bit scopes.
