Module for transforming a list of uniform random variables into a list of exponential random variables.
f(x) = lambda * exp(-lambda*x)
F(x) = 1 - exp(-lambda*x)
lambda = 1 / mu

Generates a list of exponential random variables from a list of uniforms via the inverse transformation method F(x) = 1 - exp(-lambda*x) F^-1(x) = -log(1 - x) / lambda | |
