Added examples to rspsfFit.R
Checked and saved examples. Will need to allow unrestricted estimation via try() down the line.
Renamed rspsfFit to rsFit. Docs changed to match.
Cleaned up blank sections in data files. Stopped using dwn.data as a default to rsFit - R CMD doesn't like it on check because it's an unbound global variable.
Properly marked up the generic methods for roxygenization. Must be

@S3method class generic

and nothing else. There can be NO other tags if the method is not to be documented. If it is to be documented it must have tag

@method class generic

and @export. You should never have @S3method and @method in the same documentation block.
Updated version number. Put meatier descriptions on the package dataset variable descriptions.
