* Group_layer names levels are concatenated with the specified separator character.
*
* an empty group_name_path_string (NULL or \0) will return 0
* which refers to the toplevel (indicating that no group is relevant)
*
* in case the wanted group was not found
* the result depends on the flag enableCreate.
* when enableCreate == TRUE
* the group layer (and all missing parent groups) are created
* and its item_id is returned.
* when enableCreate == FALSE
* -1 is returned (indicating that the wanted group was not found)
*
* Example (separator character '/' is assumed)
*
* layertree example
* --------------------
* toplayer id:4
* gr-sky id:3
* subgr-1.1 id:7
* layer-sun id:13
* gr-2 id:2
* subgr-animals id:6
* layer-cat id:12
* layer-dog id:11
* subgr-house id:5
* layer-roof id:10
* layer-window id:9
* layer-wall id:8
* background id:1
*
* o) a call with group_name_path_string = "gr-2/subgr-animals"
* will return 6, because the group layer with name "subgr-animals"
* can be found.
* o) a call with group_name_path_string = "gr-2/subgr-animals/flying/birds"
* will either return -1
* or create both missing groups "flying" and "birds"
* and will return the item_id of the "birds" group.
* gr-2 id:2
* subgr-animals id:6
* flying id:14 # newly created group layer
* birds id:15 # newly created group layer
* layer-cat id:12
* layer-dog id:11
* o) a call with group_name_path_string = "toplayer"
* will return -1, because this layer already exists
* but is not a group layer.
