Template:Collapsible option

Note to editors on how to manage collapsibility:
 * Use {&#123;  Template name |state=collapsed}} to show this template in its collapsed (hidden) state.
 * Use {&#123;  Template name |state=expanded}} to show this template in its expanded (fully visible) state.
 * Use {&#123;  Template name |state=autocollapse}} to show this template in its collapsed (hidden) state only if there is another template of the same type on the page. ( is usually the default.)
