STOCHRXN
STOCHRXN is the primary tool to run all the stochastic algorithms. The simulation methods and major drivers are provided as functions, and the code is designed to be as modular as possible for further extension. The users even can call these functions in their own code.

The basic outline of all the algorithms is:

• Configuration
• (inputs are analyzed and used to set key solver parameters)
• Solution Loop
• Select the step size dt
• Take a single step to t+dt with the selected algorithm
• Update the solution history
• Repeat if t<tf
• Cleanup & Output

The stochastic simulation main routines:

• SolverOptions
• StochRxn
• CollectStats
