+//! The arguments to get a path are
+//!
+//!   - radius: the minimum radius you can drive or respectively the radius you want to drive (f64)
+//!   - end_point: the point you want to end up (Point)
+//!   - end_angle: the angle you want to have in the end (Angle)
+//!
+//! The paths can be categorized into two subsections:
+//!
+//!   - The circle straight circle (CSC) paths:
+//!
+//!     - right straight right (rsr) paths
+//!     - right straight left  (rsl) paths
+//!     - left straight right  (lsr) paths
+//!     - left straight left   (lsl) paths
+//!
+//!   note: rsr and lsl paths can be constructed on every point on the plane,
+//!         rsl and lsr might return an error if the circles overlap each other,
+//!         because then the path cannot be constructed
+//!
+//!   - The circle circle circle (CCC) paths:
+//!
+//!     - right left right (rlr) paths
+//!     - left right left  (lrl) paths
+//!
+//!   note: both paths can return an error if the points are too far apart

-//! Start Vector is in the origin facing in positive y-direction
