Data sources, random/sequential generators, Equivalence classes

Put together some data sources of type string, just to be treated of samples of some ideas for discussion rather than anything in particular. They simply provide a list of strings, then a generator picks an index value to return a particular value from the list. A Random Generator picks an index value at random from 0 to List.Count. This is not guaranteed to be unique, but is reasonably unique. You might get 9 unique values and 1 duplicate out of 10 generations for example. (You would just add a Unique Random Generator if you wanted this functionality). A Sequential Generator returns each value in sequence. By default it will go back to the start of the sequence after it gets to the end of the collection, but if you specify a unique constraint during construction then it will throw an exception if it exceeds the collection.
These data sources can be used independently as Pick data sources, or consumed by Equivalence Classes for Any extensions (see CompanyEquivalenceClass example).
I also experimented with reading in data from a text file which is set as an embedded resource. I got some free sample data online that provides 500 records of people data, such as First/Last Name, City, Address etc. You can get this data for UK/US/Australia/Canada. It is initialized once and then is available during the AppDomain. At the moment, there are 3 example equivalence classes, for Any.FirstName, Any.LastName, and Any.FullName. It would be easy to do Any.Person.FirstName/LastName etc. if the number of data sources became too many...
I did not put XML comments on, but happy to do so if we decide any of these ideas are worth taking further.
Does data table automatically strip out the quotes?
