* SaTScan 10.3 parameter 'MostLikelyClusterEachCentroidDBase' has been set to 'y' by default to be in line with previous versions.
* Added an empty 'Polygons' section to the SaTScan 10.3 parameter list. Parameters can be added to it using ss.options.extra().
* Updated documentation README, package description, and rsatscan.Rmd vignette to give better instructions on how to begin a new analysis.
* Updated warning message in ss.options() if parameter is not found to suggest that the parameter might need to be specified using ss.options.extra().
