Create a hardware map file

[jasonsoohoo]

• Create a file of constants that defines all of our hardware-specific numbers.

The robot is full of code that can be reused. A way to ensure reusability is by not hard-coding values directly in the middle of our function bodies. By replacing numbers deep in code with solidly named variables we can place all of our hardware-specific / environment variables inside of a single file. This means a user can change things like motor controllers, pneumatic modules, and sensors without having to dive into the code base. All of our configurations will be available from a single location.
