How-To create random numbers
This part of liberate mostly takes the annoying boilerplate code out of standard
library functions. In particular, it provides a simple way to generate random
numbers using std::default_random_engine and std::uniform_int_distribution
as its building blocks.
It assumes that what we want most of the time is to generate random numbers of
some integer type T, within a range of valid values for that type. For
example, we might want to pick uint16_t in the range of 40 to 300.
We initialize the unsafe_bits structure with those parameters, and then
can generate as many random numbers from that as we’d like.
