------------------------------------------------------------------
@Christian: MATH-711 is now resolved, which should make your life a lot easier.
Thanks again,
Sébastien
PS: our distributions are immutable, yes, but not their potential children. See
eg {{GammaDistributionImpl}}: none of the accessors are final.

@Christian: how do you want to proceed? I intend to be done with MATH-711
in the hours to come, so if you can wait until then, it would ease the patching
process. Otherwise, your instructions for manual patching were *great*, and I
can deal with that.
Thanks again,
Sébastien

> As discussed on the mailing list
> (http://apache-commons.680414.n4.nabble.com/math-Distributions-over-sample-spaces-other-than-R-tp3931349p3931349.html),
> the distribution interfaces should be restructured.
> The most important point is to create one root interface for each domain.
> There should *not* be a common super-interace because different domains
> require different functionality. Additionally, a super-inferface would
> require to parametrize the domain which makes things more complicated (e.g.,
> "double" would have to be replaced by "Double"). Currently, Commons Math
> supports distributions with real domain and distributions with integer
> domain. Thus there will be the interfaces RealDistribution and
> IntegerDistribution.
> Another point is to drop the special cases of distributions with real domain
> in order to simplify the structure. There won't be an interface for
> absolutely continuous distributions, and there won't be an interface for
> discrete distributions on the real domain. All the functionality required by
> the special cases can be defined in RealDistribution.
