/**
* Parse the current URI and return the EDK arguments.
*
* This returns an ordered array of parameter arrays. Each parameter array
* contains name, value (or true if no value), true/false depending on
* whether it was in the pathinfo or querystring.
*
* The first two components from path info will be labelled 'a' and 'id'.
*
* pathinfo is treated as kburl/index/page(a)/id/name/name
* e.g.
* http://killboard/path/to/kb/index/kill_detail/45/unlimited
* returns {0=>(a, kill_detail, true), 1=>(id, 45, true), 2=>(unlimited,true, true)
* http://killboard/path/to/kb/index/kill_detail/?id=45&unlimited
* returns {0=>(a, kill_detail, true), 1=>(id, 45, false), 2=>(unlimited, true, true)
* http://killboard/path/to/kb/?a=kill_detail&id=45&unlimited
* returns {0=>(a, kill_detail, false), 1=>(id, 45, false), 2=>(unlimited, true, true)
*
* @return array
