GetEpsilon solve the floating-point accuraccy problem.

There is the floating-point accuraccy problem, so instead of checking against zero, some epsilon value has to be used. Because the size of the pdp value depends on the length of the vectors, no static value can be used. One approach is to compare the pdp/area value to the fraction of another area which also depends on the length of the line e1=(p1, p2), e.g. the minimal area calucalted with PerpDotProduc() if point still not on the line. This distance is controled by variable accuracyPointOnLine
