Station authority level "L,R,L+R"

Station authority level "L,R, L+R" adds multilevel access support. Control access can
also be simultaneously permitted from local or remote location. Simultaneous local or
remote control operation is not allowed as one client and location at time can access
controllable objects and they remain reserved until the previously started control
operation is first completed by the client. Control access with IEC 61850 originator
category station is interpreted as remote access.
