[Rd] Suggestion: User defined sampling

[Ralf Stubner]

Hi everybody,

Currently one can alter R's random number generation via RNGkind() in
three aspects: the RNG itself, the method for drawing from the normal
distribution and the method for generating integers within a range.
For the first and second aspect it is possible to supply user defined
methods. This is not the case for the last aspect, which is handled in
R_unif_index. I think it would be interesting to add a comparable hook
there as well. What do you think?
