%description
Provides a simple to use, intuitive, and extensible interface to several
stochastic simulation algorithms for generating simulated trajectories of
finite population continuous-time model. Currently it implements
Gillespie's exact stochastic simulation algorithm (Direct method) and
several approximate methods (Explicit tau-leap, Binomial tau-leap, and
Optimized tau-leap). The package also contains a library of template
models that can be run as demo models and can easily be customized and
extended. Currently the following models are included,
'Decaying-Dimerization' reaction set, linear chain system, logistic growth
model, 'Lotka' predator-prey model, Rosenzweig-MacArthur predator-prey
model, 'Kermack-McKendrick' SIR model, and a 'metapopulation' SIRS model.
