This class computes the semantic classifier distance between 2 points. It is defined as
the alpha coefficient in the above formula the beta coefficient in the above formula

This function computes the distance between the two given points.
It needs to be implemented in each subclass. It takes as optional arguments the number of the segments on which to operate.
Implements gaia2::DistanceFunction.
