Switching context

Switching from public key, private key, elliptic curve, diffie-helmann, elgamal, polynomial basis, optimal normal basis, etc to path planning, obstacle avoidance, localization, mapping, actuator, reactive, deliberative, hybrid, quadtree, and so on.

Wish me a smooth and quick switching back to my “origin” after finishing this 🙂

[trying to do them in parallel 80:20 or 70:30, still don’t know if it works]
