/**
 * Return a numerical approximation of the integral
 * of the function `f` from `a` to `b` using Monte Carlo integration.
 *
 * Thoughts for future improvements:
 * - use a MISER algorithm to improve the accuracy
 * - use a stratified sampling to improve the accuracy
 * - use a quasi-Monte Carlo method to improve the accuracy
 * - use a Markov Chain Monte Carlo method to improve the accuracy
 * - use a Metropolis-Hastings algorithm to improve the accuracy
 * - use a Hamiltonian Monte Carlo algorithm to improve the accuracy
 * - use a Gibbs sampling algorithm to improve the accuracy
