* register_taxonomy() - Create or modify a taxonomy object.
* register_taxonomy() - Create or modify a taxonomy object. Do not use before init.
*
* A simple function for creating or modifying a taxonomy object based on the parameters given.
* The function will accept an array (third optional parameter), along with strings for the
* taxonomy name and another string for the object type.
*
* The function keeps a default set, allowing for the $args to be optional but allow the other
* functions to still work. It is possible to overwrite the default set, which contains two
* keys: hierarchical and update_count_callback.
*
* Nothing is returned, so expect error maybe or use is_taxonomy() to check whether taxonomy exists.
*
* Optional $args contents:
* hierarachical - has some defined purpose at other parts of the API and is a boolean value.
* update_count_callback - works much like a hook, in that it will be called when the count is updated.
* rewrite - false to prevent rewrite, or array('slug'=>$slug) to customize permastruct; default will use $taxonomy as slug
* query_var - false to prevent queries, or string to customize query var (?$query_var=$term); default will use $taxonomy as query var
*
* @package WordPress
* @subpackage Taxonomy
* @since 2.3
* @uses $wp_taxonomies Inserts new taxonomy object into the list
* @uses $wp_rewrite Adds rewrite tags and permastructs
* @uses $wp Adds query vars
