599,uniform_01 copies engine instead of using a reference,uhoreg,jmaurer,"{{{
In the uniform_01 class, the constructor takes a
base_type (i.e. the random number generator) as its
argument, and the _rng member is just a base_type. 
This results in uniform_01 copying the random number
generator, along with its state.  Thus if one creates
several uniform_01 objects (e.g. one at the beginning
of each of several functions), they will all return the
same random numbers.

The constructor should take a reference (i.e.
base_type&) as its argument, and the _rng member should
be a base_type&.  (Indeed, the documentation at
http://www.boost.org/libs/random/random-distributions.html#uniform_01
says that the constructor takes a base_type&.)
