Work on ODE test problem: reaction

 - Add method and tolerance as arguments to program
 - Add script for running series of benchmarks
 - Add current benchmark results

Some initial results:

 - Both cG and mcG converge, but convergence could be better
 - mcG terribly inefficient with current parameters
