Detailed Description

template<class T>
class line::ssa::NrmEngine< T >

The NRM engine: the reaction network built from sn, and the sample path.

It is a class rather than a chain of free functions because the run loop threads eight pieces of mutable state (the population vector, the per-node buffers, the in-service phase multisets, the clocks, the propensities and the three metric accumulators) through every step, and the reference threads the same eight as arguments to a single 700-line function.
