Subject: [boost] [random] Request for Additional Generators

I would like to request the addition of 2 generators to Boost.Random.
Web page: http://xoroshiro.di.unimi.it/
A very fast PRNG, (quite a lot) faster than the fastest current boost
generator, with a period of 2 ^ 128, which could/would be good for f.e.
game programming (except for shuffling, see below). It also has a state of
only 16 bytes on x64. The author states that the distribution is of higher
quality than f.e. MT19937-64
It's probably best to just read the web-page, as it goes into quite some
detail and is in itself the summary of the research conducted in this area.
Other than the normal boost complications, it's very easy to implement and
I use my simplistic implementation to great satisfaction with the std and
article on CodeProject the issue of shuffling is raised. It's appears that
shuffling of large arrays of data requires a generator with extremely long
periods in order to be able to generate all the possible permutations. To
this extent I would like to see in boost a generator like George
or/and a templated SFMT generator like this
