Erg project

A display for Concept 2 Model C rowing machine.

Math/physics behind the erg monitor found here: http://www.atm.ox.ac.uk/rowing/physics/ergometer.html

On concept2.com forum found that moment of inertia for models B, C, and D is equal to 0.1001 kg/m^2

A lot of code is stolen directly from libopencm3-examples. Namely the following ones:

adc-dac-printf
usb_cdcacm
tick_blink
lcd-dma
lcd-serial (font)
