I had planned on creating Year as a Select element for my application, 
and it did feel strange that I was recreating something that the Date 
element already provided itself.

YearSelect and DateSelect sound good to me, if for no other reason than 
the clarity these names provide.

I'll try the Date inflator... I'm new to FormFu and wasn't aware that an 
error in the inflation stage would return an error to the user, but I 
guess it makes sense.

I originally tried to use the AutoSet constraint on the Date element, 
assuming that it would magically be applied to each individual select 

Thanks Carl!
