Functions to check performance of distribution and quantile functions. Applying the distribution function followed by the quantile function to a set of numbers should reproduce the original set of numbers. Likewise applying the quantile function followed by the distribution function to numbers in the range (0,1) should produce the original numbers.

Given a density function specified by the root of the density function name, returns the integral over a specified range, usually the whole real line. Used for checking that the integral over the whole real line is 1.
