To include several test functions relevant in reliability analysis exercises (see for example Issue #267), the Weibull distribution should be added to the code base. The density function of the distribution reads:
$$ f_X(x; \alpha, \beta) = \frac{\beta}{\alpha} \left( \frac{x}{\alpha} \right)^{\beta-1} \exp{\left( - \frac{x}{\alpha} \right)^\beta}, x > 0; $$
where $\alpha >0$ and $\beta > 0$ are the parameters of the distribution.
