Create a GroupFinder

[dataApps]

ComposisteFinder allows one to combine multiple Finders into a single Finder.
If any of the component Finders find a match then its reported. If multiple compnent Finders find a match, they are all reported.

To detect Quasi identifiers, we need a GroupFinder, one which reports a match only if all the component finders detect some element in the text - eg. (name, zip code , dob)
