Added
-----

- Changelog, license, readme.
- Cargo new lib template (including gitignore).
- Geometry module:
    - basic geometry data structures `Point` and `Pose`,
    - `::new(arguments)` constructors,
    - `::default()` constructors,
    - rotate `Pose` around `Point` computation.
- Properties module:
    - `Motion` (speed, steering) and `Size` data structures,
    - `::new(arguments)` constructors,
    - `::default()` constructors,
- Bicycle car class `BCar` and its constructors (with arguments, default, with
  pose).
- Basic geometry computation:
    - minimum turning radius (MTR),
    - left/right circle center of MTR,
    - perfect parking slot computation.
- Drivable zone computation.
- Iterator trait implementation for `BCar`.
