function taxonomy_menu_taxonomy in Taxonomy menu 6.2

Same name and namespace in other branches

1. 5 taxonomy_menu.module \taxonomy_menu_taxonomy()
2. 6 taxonomy_menu.module \taxonomy_menu_taxonomy()

Implementation of hook_taxonomy().

When a user inserts, alters or deletes taxonomy terms, we can keep the related menu synchronised to the changes without rebuilding the entire menu (which would delete all other customisations the user may have done).
