random::normal_distribution always returns a NaN when presented with a UniformRandomNumberGenerator that provides values outside the range of (0,1).

So, for example, this will print a NaN.

#include <boost/random.hpp>
#include <iostream>

int main(int argc, char *argv[])
{
        boost::mt19937 eng(40);
        boost::normal_distribution<> norm(0,1);
        std::cout << norm(eng) << std::endl;
}

Looking at the code, it is clear that for normal_distribution's answers to be defined, the values need to be in the range (0,1)

The attached patch uses uniform_real to restrict the range to [0,1).  Unfortunately, this leaves 0 as a fail point.  I don't see a clear way to fix that at the moment.
