Random generator class

I was involved into a project over the winter where we didn't have any data to fead the system, even though we had the format (or at least a fairly clear idea of it) in which each data file should be. So I wrote a class to randomize the data for creating several different .dat files. I did a bit of digging at the time, and even though I can't recall where I found the list I've used into the Enum, they were at that time the most popular one in the UK. I've had a lot of fun working my head around this, using Enum for the first time!

I am looking forward to improve this pet project (creating random list of comma separated item) by taking the Enums out of the code and putting them into on or more xml files.
