this wordpress plugin allows hierarchical checklists to be checked up/down the tree

feature list:

• checks parent when checking a child item
• on parent selection all childs are selected
• settings page under tools menu to choose which taxonomies to work with
• this can also be used on frontend

to use at the front end :

the output of wp_terms_checklist must be wrapped in 
<ul id="{termname}checklist" > 
{wp_terms_checklist}
</ul>

This is on GitHub so let me know if I've done it worng somewhere.

thanks to Mr. Ryan Sechrest and his code, from which the inspiration to this, and some handy implementation hints, came.
