Contributing to DateTime::Event

Hi everybody,

I've not been using DateTime for very long and got recommended it by our
hosting partners, really happy with it etc... But I've come across a
situation where I want to do something standardish with it and there
doesn't seem to be any provision for it. The reason I'm mailing the list
is that I'm amazed no-one has done this before which is leading me to a
suspicion that there's a good reason why! 

So, what I want to do is get the the Bank Holidays for the UK and a few
other methods like 'is_this_a_bank_holiday( $dt )' or perhaps something
like 'number_of_working_days_in( $dt1, $dt2 )' to take into account
weekends. And so on as the project I'm working on requires. 
Now, the reason I think this is possible is that looking at:
http://www.berr.gov.uk/employment/bank-public-holidays/index.html
The dates don't appear to be particularly random (they all have v.simple
rules) and the only dates I don't really understand, the easter ones,
I'm planning on using DateTime::Event::Easter to help me out. 

Is there anything obvious anyone can see that I'm missing, or any
problems with doing this? I'd imagine I'd call this module
DateTime::Event::BankHolidays::UK|England but I'm getting a bit ahead of
myself now.

Ta,

Kristian
