To include several test functions relevant in reliability analysis exercises (see for example Issue #267), the exponential distribution should be added to the code base. The density function of the distribution reads:
$$
f_X(x) = \lambda e^{(-\lambda x)},
$$
where $\lambda > 0$ is the parameter of the distribution.
