Point reduction algorithm
Two approachesFirst approach
Kicks out points based on direct neighbours
Good for initial cleanup of the track
Second approachKicks out points based on importantness
Good for refinement of a clean track

Second approach
Idea: Mark vital points. Kick out all points that are not vital points.
Start point and end point are vital.
Repeat:Find point with maximal d when compared to its
neighbour vital points.
This point is a new vital point.
Until the limit is reached.

Final words
Final algorithm will be a combination of both approaches
Final algorithm already implemented in C for testing purposes.
We need to convert coordinates to distances (not trivial)
Calculating d can be done using basic mathematics
