Detailed Description

A templated class for sampling from a set of objects with given probabilities. Uses MyDiscreteSampler.

Provides a simple and efficient way of sampling a discrete probability distribution as described in http://www.jstatsoft.org/v11/i03/paper Instances can be reused by calling the Prepare method every time you want to change the distribution. Sampling a value is O(1), while the storage requirements are O(N), where N is number of possible values

Beware that Cestmir thinks this can be less precise if you have a billiard numbers.

He is probably right. So only use this version if you don't care.
