Detailed Description

Distrbase_: an abstract base class for univariate continuous distributions.

Classes derived from this base shall be able to return the probability density function (PDF) and the cumulative distribution function (CDF) at a given point, calculate the probability of a given interval, calculate the mean, variance, skewness, kurtosis,entropy etc. of the distribution, generate random numbers from the distribution.
