Detailed Description

Performs the setup of the Metapop and SimComponents and runs the simulation.

This class implements the two main loops of a simulation, the replicate and the generation loops. The replicate loop iterates the generation loop which itself iterates the life cycle loop composed of the LCEs selected by the user. A SimRunner brings together the basic simulation components and a metapopulation on which they act. It perfoms the setups necessary to have a Metapop ready for the simulation and runs the different simulations stored in its ParamManager base class. Also hosts the file and stat services.
