CG Scale Mods

This is a couple of modifications to a pretty cool load cell RC glider center of gravity project found here:https://github.com/olkal/CG_scaleI
I have added an LCD case for the 16x2 Arduino I2C LCD, I also wrote a new codebase for the I2C module only, a different, more readable, and ever so slightly more accurate method of calculating CG (note that real life model will not notice this change). I also removed the LED and Battery voltage since the LCD backlight kinda does those functions for you.
I added a discreet switch to change the display between grams and mm, to pounds and inches.
I added a 10mmx2mm magnet on one frame cover and the LCD case so that the LCD can stay attached to the frame cover.
You can get the pins used from the arduino sketch, but for the Switch it is a Ground and pin 5, since I intialized it too a pull-up, the switch connects it to ground.
I2C LCD has the clk on pin A5 and data on pin A4
