fieldsets

Hi
I am trying to get a fieldset working in webform underthe omega theme.
Basically what I want to do is to have a hierarchy as follows
Name of person
Gender
Age
Style of Archery

I figured my first attempt at a custom and hopefully contributed module should be something that is simple and usable, while a little bit challenging.

I love the simplicity of the FAPI collapsible fieldset but I was disappointed that it didn't remember whether I wanted it to be collapsed or open. So this is my attempt at fixing that problem.
