[Ns-developers] Random Variable API Changes / bugs 181 and 229

[Michele Weigle]

Here's the patch (based off of the ns-3-rng-changes branch).

The only remaining issue for me is the meaning of 'bound'.  In the  
NormalVariable implementation, the true bound is (mean +- bound).  In  
the others (Exponential, Pareto, Weibull), bound is the maximum value  
that can be returned.

I made a couple of changes in the NormalVariable comments to reflect  
this meaning of 'bound'.
