1. Design Phase
  a) Get familiar with existing stable physics libraries (Chipmunk, Box2D) and design APIs (both C APIs and Pygame wrappers).
  Goal: Neat, Simple, Clear.
 I will publish and discuss it in the community. (5.1 to 5.10)
 b) Detail design of both modules and algorithms
 Goal: Easy to implement and flexibility for future extensions
 I will also publish and discuss it in the community. (5.11 to 5.20)
2. Coding Phase
 a) Module coding phase: implement core physics modules in C. DO Unit Tests after each module. (A Detail Code Plan will be out in Module design phase) (5.21 – 7.10)
 b) Module wrap phase: Wrap C API to Pygame API, make a layer combining rendering and physics simulation. Lots of unit tests will be done too.(7.11 – 7.20)
3. Final Test Phase and Demo Phase
 a) Design and implement a simple physics simulation demo with Pygame and the physics library. (7.20 – 7.31)
 b) Program test, performance profile and comparison to other libraries will be done.(8.1- 8.5)
 c) Documents of the APIs and how to use and the future road map will be written and published to the community.(8.6 – 8.10)
 d) Release both the library binary, source codes and documents to the community, let everyone test it and send useful feedbacks and bug reports.
4. Maintain it and future development
