f7ca6ca889 Bernoulli reenabled -- using integral type for the discrete_distribution, but 
then casts in the fill

ec4a9b7f6c The Bernoulli gives a no compile due to a static assertion that the type be integral 
in 4.7 random.h

Probably need to go through an Integer type, and then conver to real after the random draw
to make clean.

08edbb5cbe HMC bit repro across checkpoints. Fixed parallel RNG issue with threading. 
Conclusion: c++11 distributions not thread safe and must us distinct dist as well as distinct engine
per site. Makes sense when you think of box muller. Also added a reset of dist on fill to ensure
repro across checkpoints.

5710966324 Options to use mersenne twister OR ranlux48 via --enable-rng flag at configure time. 
Can save and restore RNG state via new (serial) I/O routines in a NERSC header style file.
Store a Parallel (one per site) and a single serial RNG file.

4e085dd0ed Domain wall even-odd 2f HMC with wilson gauge and PV 2f ratio now running and giving small dH. 
Azusa is working hard on the rectangle term and we'll hopefully start reproducing plaquettes
from RBC-UKQCD parameters soon !

My new laptop is pretty warm and is starting to groan ;)
