I envision a repository of modules that could be placed into the default code?

Say different steering modules

Instead of having anything quite concrete in default code from IFI, have comments saying insert choice of steering here and go on from there.
Also maybe a graduated default code base?
Start with one with the comments said above with a dead-reckoning auton.
Release a version that has more instructions for pid, encoders, et all

In terms of modules:
Steering Module: Pick Tank, Truck, Car, Crab, anything and you insert the code either into where the comments said or into the project. Albeit, the code should NOT be 100% completed but maybe 75% so the rookie programmer can fully understand it to complete it.
