Detailed Description

Interface for the 2 dimensional vector module.

Todo:

Complex operations on vectors and implementation of the <french> reperes </french>

Test:

polar -> cartesian & cartesian -> polar seems to be ok.

This module provides functions to handle 2d vectors and basic geometry fucntions.
