Model Setup

writeparams(data::Dict,fname="light.yml"::String)

Replace the data in the yml file fname to the new dictionarydata`.

If fname is unspecified, use light.yml as the default file name.

readparams(fname="light.yml")

Read parameters from yml file fname.

If fname is unspecified, use light.yml as the default file name.
