PyMata Version 2.01 Released

This is an exciting new release that is compatible with Python 2.7 as well as 3.4. 

It also introduces callbacks for detected Analog, Digital, i2c read, and encoder data changes.

Callbacks can be attached to a PyMata analog or digital "data latch" providing callback event notification when a preset data threshold has been crossed. For example, you can set an analog latch to provide notification when the data on the pin achieves a value that is greater than, greater than or equal to, less than or less than or equal to, a value of your choosing. For digital pins, you can select a latching notification with that fires when the pin goes from 0 to 1 or 1 to 0.
