/** MO-LR protocol state machine.
This class manages the MO-LR protocol procedure and is employed when the protocol
module is required to handle interactions for a mobile self-locate.

The class implements the pure virtual methods defined by CSuplFsmSessionBase.
@see CSuplFsmSessionBase

The class also implements a timer observer interface defined by MLbsCallbackTimerObserver
@see MLbsCallbackTimerObserver
