Method WHOLE_TRACE_INDEP_DIST

WHOLE_TRACE_INDEP_DIST stands for "whole trace independent distance". With this method the largest distance is measured between a line between the end points of the profile and the trace. If this distance is bigger than CVAL the profile is considered as curved.

Thus, if d > CVAL then the profile is considered as curved.
