006/**
007 * This is a simple speed matcher which will speed match a locomotive to a given
008 * start and top speed using the complex speed table. Speed steps 1, 10, 19, and
009 * 28 will be set according to values interpolated linearly between the given
010 * start and to speeds. Values for the remaining CVs will interpolated between
011 * these 4 CVs. This is done to reduce the time the speed match takes and to
012 * increase likelihood of success.
