In the current implementation the dimension has a different interpretation for
continuous and discrete pdfs. For continuous pdfs it is the dimension of the
state vector for discrete pdfs it is the number of discrete states.
This is quite confusing.

Patch to get unique interpretation of dimension
In this patch a propose a solution to have a unique interpretation for the
dimension.
To this end I introduced an extra state variable _num_states for discrete pdfs
(and discrete conditional pdfs), which is the number of discrete states. The
dimension of a discrete pdf is automatically set to 1 (since it is just and
integer).
Any commments, suggestions?
