val exp_01 : float -> float t -> float t

The function f(x) = exp(k * (x - a)) - b ...where a and b are chosen so that f(0) = 0 and f(1) = 1. The k parameter controls how sharp the curve is. It approaches a linear function as k approaches 0. k = 0 is special cased as a linear function for convenience.
