'par' Structure: User instructions for FitSpec

The FitSpec function is capable of fully automated spectrum fitting, without additional user instructions aside from the spectrum itself. However, many situations will require some adjustments by the user to fully optimize the fitting. The ‘par’ structure gives the user control over most aspects of the spectrum fitting. The details of each field for user instructions is given here, although one should also note that the ‘par’ field is output by the FitSpec function as ‘fit.par’, and contains the settings either chosen by FitSpec or set by the user. This is useful when optimizing fitting parameters, as one can see the initial parameter settings determined by FitSpec, and then optimize those deemed to be suboptimal.
