Detailed Description

This class composes the breakpoint function specified by its pairs of (split point, value) with the given distance.

Parameters

distance	the name of the distance to apply the BPF to.
params	the parameters for creating the distance we compose with.
breakPoints	the pairs (split point, value) that define the BPF.
