* Allows external systems to push grade items and scores into the course gradebook. The service as to be
* activated by the site admin.
* A typical usage requires two calls, the first to create/update the grade item and the second to update
* the user grade. The create/update grade item call should not pass null for the grades. The update user
* grade call may require the identity_type flag which can be passed either in the grades parameter or in
* the itemdetails paramter. The latter is otherwise not required.
*
* @param string $source - Any string or empty.
* @param string $courseid - Expected idnumber or Moodle id; requires identity_type in itemdetails.
* @param string $itemtype - Ignored; all mhaairs items should be manual.
* @param string $itemmodule - Ignored; all mhaairs items should be identified as mhaairs.
* @param string $iteminstance - The mhaairs assignment id.
* @param string $itemnumber - Any integer.
* @param string $grades - Url encoded, json encoded, array of the following user grade details:
* userid - The user username or internal id (depends on identity_type). Required. PARAM_TEXT.
* rawgrade - The user grade. Optional. PARAM_FLOAT.
* identity_type - Whether to treat the userid as username or internal id. Optional. PARAM_ALPHA.
* @param string $itemdetails - Url encoded, json encoded, array of the following item details and flags:
* itemname - The item name. Required. PARAM_TEXT.
* idnumber - The item idnumber. Optional. PARAM_TEXT.
* gradetype - The item grade type. Optional. PARAM_INT. Defaults to point.
* grademax - The item grade max. Optional. PARAM_FLOAT. Defaults to 100.
* hidden - Whether the item is hidden. Optional. PARAM_INT.
* deleted - Whether to delete the item. Optional. PARAM_INT.
* categoryid - The name of the target category for the item. Optional. PARAM_TEXT.
* identity_type - Whether to treat the courseid as idnumber or internal id. Optional. PARAM_ALPHA.
* needsupdate - Optional. PARAM_INT.
* useexisting - Whether to use an existing item by name. Optional. PARAM_INT.
