Method SynchronizeInputLink

Core/ClientSML/src/sml_ClientWorkingMemory.cpp:651–761

* @brief This method is used to update this client's representation * of the input link to match what is currently on the agent's * input link. * * NOTE: This is the reverse of how a client normally uses the input link * but can be useful for tools that wish to debug or monitor changes in the input link. * * NOTE: If two clients try to modify the input link at on

*        make any guarantees about what will or won't work.
