Detailed Description

Defines the GraphNetwork class for representing and evolving nuclear reaction networks as a heavily connected graph.

This file provides the GraphNetwork class, which implements a graph-based nuclear reaction network using REACLIB reactions and supports both stiff and non-stiff ODE integration. The network is constructed from a composition and can be queried for species, reactions, and stoichiometry.

This is a general nuclear reaction network; however, it does not currently manage reverse reactions, weak reactions, or other reactions which become much more relevant for more extreme astrophysical sources.
