Add robot-side Bling subsystem

[kevlam2706]

Add a Subsystem class to support the Bling. It will need to maintain a link to the Arduino via RS232 to tell it what to signal.

There is existing code that we wrote from 2994 that we can port over into the command-based robot code.

Here's the link to wpilib's tutorial on command-based programming:

We want to build a Subsystem that can later be controlled by Commands.

We will need to get a serial cable to connect the RoboRio to one of the Arduino boards (to be later replaced by a Roboduino). Hopefully @LlamaBot9000 (miniKev) can help us with this.

Found some bling interface code from 2994 - https://github.com/FRC2994/FRC-2015/blob/927aa2e77c47a2a32f1878d380ce181c6c7583dd/src/ca/team2994/frc/robot/Bling.java

@greyingjay in the example code you give me, they are referring to a boolean variable called "blingport". What are we going to use for this? I think that this variable refers to the port between the arduino and the roborio, so are we also going to have something similar? Subsystem.blingPort.writeString("X");, if (Subsystem.blingPort != null)

Is it just a USB B cable that we need or is there something special to interface with the roborio (that goes in the same port as the navx)

@eAUE try this link, it is a tutorial for the I2C connection code

[KyleRAnderson]

This is well under way. Should be committing a good version soon.
