Empirical distributions are discrete by nature. Depending on the underlying
data, the domain is usually (a subset of) the reals or the integers.
However, after moving probability(double) to Distribution,
DiscreteDistribution will be an empty interface. Thus there is in fact the
question whether it should be eliminated. Otherwise it would be just a
"flag" for discrete distributions and that's indeed independent of the
sample space.
