P	the type from which to sample and score the value
RNG	the type of PRNG used
Ts	the parameterization of the record

Parameters

r	the record in which to store a node_t<D>
address	the address at which to store the node
dist	the distribution from which to sample and score the value; the proposal distribution
rng	the PRNG used
