@simplify_radial_distance_t(nim, tol:numeric)


builds a new simpler nim by aggregating consecutive breakpoints whose images are wihin a distance of tol (for each component independently)

In the simplification process, a breakpoint is assimilated to a d dimensional point for a nim with dimension d (in other words, the x part of the breakpoint is not taken into account). This is the case for all nim simplification functions that end with a _t.

It reduces successive vertices that are clustered too closely to a single vertex, called a key. The resulting keys form the simplified polyline. This process is illustrated below:
