OCR H446 2.1.1: Thinking abstractly

The free BugBot lessons that teach this point, a robot to try it on, and the past-paper questions that test it.

Lessons that teach it

1. A2.4 Abstraction and models Recursion and computational thinking
   Representational abstraction, generalisation, problem reduction, and a grid model of the mat that differs from reality.
2. A2.5 Procedural, functional and data abstraction Recursion and computational thinking
   Information hiding, hiding the values, the method and the representation, and swapping a data type's insides.
3. A2.10 Project: out of the dead end Recursion and computational thinking
   Model a maze, solve it by recursive backtracking, and drive the robot out along the route.
