Add simple tests - good as initial tutorial

[teviopl]

Hi

Just added simple tutorial test - as I could not find any simple example how to start using the validator.

Hmm, do you mean the Javadocs are not enough?

I'll look at the patch.

Actually there is a problem: format attribute date is no more in the main package, and the bday in the sample data does not obey the format (a date is supposed to be of the format YYYY-mm-dd).

I am closing this one, since there is now a full examples package with links to source code and sample files.
