Wrap Nicki's Scrubber into a module

[Gordonei]

Incorporate Nicki Tiffin's address scrubber. First step is to wrap it into a module, similar to the Basic Scrubber.

The scrubber makes use of some proprietary datafiles. The module should presume that the files will be available, for reading, in a directory passed in at the Scrubber object's instantiation.
