 * This function can be thought of as a reverse to PHP5's http_build_query(). It takes a given query string and turns it into an array and

 *
 * - ?key[subKey]=value
 * - ?key[]=value1&key[]=value2
 *
 * A leading '?' mark in $query is optional and does not effect the outcome of this function.
 * For the complete capabilities of this implementation take a look at HttpSocketTest::testparseQuery()
 *
 * @param string|array $query A query string to parse into an array or an array to return directly "as is"
 * @return array The $query parsed into a possibly multi-level array. If an empty $query is
