Detailed Description

Helper class for the scan methods.

Store several parameter points that are needed at various points at the scan. The points are handled in the format of RooFitResults, hence the name. We need

• the parameters at a function call so they can be restored once the function is done
• a round robin database to hold the N last fit results, so that in the plugin scans we can refit multiple times with varying start parameters
