I needed an accordion effect, but all I could find were either heavy or
had too many requirements. So, I rolled my own...
Any responses are welcome!

If you have any problems with the attachments, please let me know. Since
I'm going through employment changes, I don't have a server to post
examples on (yet ;-) ).

I needed an accordion with as little requirements as possible,
and that was lightweight. You can look at the example using various
elements and see that you don't need specific classnames/ids for
individual parts of the accordion, nor do you need to have specific tag
types. It is the structure that is key here. I've added the ability to
add options based on the accordion header classnames, such as: lock
individual partitions of the accordion by assigning the header a
classname of "locked" (look at accordion 4 in the first example), or
allowing an active partition by assigning the header a classname of
"active" (look at accordion 2 in the first example, this allows one
partition to stay open at the beginning). The current options allow for
adding actions to open or close all accordion elements for all
accordions (look at the options for the first example). I hope to be
adding more features and unit tests soon! I am open to any suggestions
or feature requests, and bugs (I think I finally conquered the Blind
Down jumpy bug).
