These types of sampled probability distributions are very
useful. In my field of work they are now more important
then the classical functional distributions like Gaussians.
The advantage is of course that to arbitary precission they
can represent any distribution.
I would suggest a common name such
as 'parametric_distribution' or 'sampled_distribution'
The sort of distribution can be represented in many ways
the two major (and interchangable) are as sorted
probabilties or as cumulative probabilites.
One problem with this concept (a single draw from a
distribution) is that it is O(n) where n is parameter table
size. However multiple draws can be simplified, by sorting
and then searching in the parameter table. At present boot
random has no concept for multiple draws. Because of the
complexity issue the paramertised_distribution doesn't seem
that useful without also a multiple draw concept.
In summary either add both or none!

The new standard will contain a discrete_distribution, which returns an integer given a sequence of weights.
