Returns a list of all currently loaded layers.
Only layers loaded in the current editor mode are listed. For example, if a layer is added in the OME, then it becomes part of the base layer, once the mission is previewed, and is not listed in the RTE layers anymore. If a layer is added during the preview (in the RTE), then it is deleted, once mission preview is aborted, and is not listed in the OME layers anymore.
|Return Value:||Array - List of layer names.|
