stepan 448be1e6f2 Added new function. This function computes the mean of a prior
distribution (gamma, inverse  gamma 1 and 2, beta)  given the mode and
the variance.

stepan 01ba142329 v4.1:: Changes related to the gamma variate generator.
+ Changed headers.
+ Allows vector of coefficients when calling the Beta random generator.

stepan a05b5e9481 v4.1:: Changes related to the gamma variate generator.
+ Added algorithms from Devroye (1986, chapter 9).
+ Now we can generate independent gamma variates (and, as a consequence, beta)
with parameter a  <= 0.5. This was not possible  with the algorithm of
the previous version.
+ Algorithms are specialized depending on fix(a)=a, a<1 or a>1.
+ This new version can handle  vectors for a and b (same length).
