Explanation

FrankenEmu is an emulator designed to interpolate among a collection
of numerical N-body simulations called the Coyote Universe.

It uses a Gaussian Process interpolation between a set of simulations
arranged in a Latin Hypercube in parameter space.

Each simulation yields a non-linear matter power spectrum P(k,z), and
the interpolation is between these spectra, so the output should be a
reasonable (1% accuracy) value of P(k,z) for the given parameters.

The simulations and the whole process are explained in detail in the papers
above.

##Parameters

These parameters can be set in the module's section in the ini parameter file.
If no default is specified then the parameter is required.

##Inputs

These parameters and data are inputs to the module, either supplied as parameters by the sampler or computed by some previous module. They are loaded from the data block.

##Outputs

These parameters and data are computed as outputs from the module
