Detailed Description

Class to generate input dispersions for the simulation.

The dispersion engine class is used to generate input dispersions for use in Monte Carlo and similar simulations. It generates dispersion values which parameters and inputs on models can map to, allowing for full dispersion-->model traceability.

The dispersion engine registers dispersions
