Code Formatting: append all variables which contain units with their units

[ElectricRCAircraftGuy]

This is a sub-issue of #11. Don't close #11 until all sub-issues are resolved.

I will help with this. Just want to teach the principle too is all since you'll write code faster than I can reformat it :).

Instead of:

int some_var;

Do:

 int some_var_mm; // millimeters
 int some_var_m; // meters
 int some_var_mps; // meters per second
 int some_var_n; // newtons
 int some_var_psi; // PSI
 int some_var_kpa; // KPa
 int some_var_ms; // milliseconds
 // etc etc
