# objects can be named in two ways:
# 1. In UE Editor, select and object and change its name to something else. Note that you must *change* its name because
#    default name is auto-generated and varies from run-to-run.
# 2. OR you can do this: In UE Editor select the object and then go to "Actor" section, click down arrow to see "Tags" property and add a tag there.
#
# The simGetObjectPose and simSetObjectPose uses first object that has specified name OR tag.
