Distance from a point to a line (so it's the perpendicular distance).

1	perpendicular.distance(b, m, x, y)

Find distance from a pt (x then y coords) to a line segment given as start and end points. Either x, y or end points can be vectors, but not both.

It first finds perpendicular distance, then distance to each end point, and returns the minimum.

If both b, m and x, y are vectors, they must all be same length.

Note check for infinite slope, meaning that the intercept b is the x-intercept.
