set_item_to_curelem
Assign a class to the current element.
Handling:
int err = ac_request("classification","set_item_to_curelem", iGuidItem);
Here:
err = 0 if assigned without error,
iGuidItem - a handle to the guid value of the class.
Before calling this function, you must create an object of type ts_guid. When it is created, we are given a descriptor.
Then we find the required class in the required classifier by name through "find_item_by_name" and get the guid of the class.
