  Add the possibility to add and remove a component in discretePdf. This is needed for the Mixture of Gaussian as discussed in: http://lists.mech.kuleuven.be/pipermail/bfl/2007-December/000822.html

Patch seems ok. 2 small remarks: - Try generating your patches using svn diff -x -u, so they are somewhat more readable. - I think you should make the documentation about stateAdd somewhat more explicit, in casu about the meaning you attach to the parameter "probability p". As I understand from your patch, this is the probability of the new discrete state _after_ renormalizing? Anyway, from your doxygen comment, this is not clear to me. As an example, suppose I have a discretePdf with state 0: prob 0.5 state 1: prob 0.5 When I now perform a pdf.stateAdd(0.5), this will result in state 0: prob 0.25 state 1: prob 0.25 state 2: prob 0.5 However, I could also expect it to be state 0: prob 0.33 state 1: prob 0.33 state 2: prob 0.33 You should be more explicit in the docs about this behaviour I guess. Thx for your contribution!

  Created attachment 176 Updated patch Thanks for the feedback, I made a new patch and: * Added a Changelog message [1] * Make a better unit test, checked all states. * Change the variable names, so it won't create any confusion with probability.
