program a workout into the erg from the library

[MoralCode]

Programming a workout into the erg is done by sending CSAFE commands to the C2 PM control service's transmit and receive characteristics.

These commands are documented somewhat in the Concept2 Communications Interface Definition rev 0.19 and are based on the Fitlinxx CSAFE Specification.

Because this CSAFE spec was developed "with input from many contributing manufacturers including Precor, Quinton, Schwinn, Stair Master, Star Trac, Tectrix, Trotter, and Life Fitness" and we will need to implement some parts of it in order to get workout programming, I have started working on a library to take care of formatting the data so that it can be sent to the erg via the service mentioned above.

This should be roughly implemented as of v0.1.3, but still needs testing
