 #### Command handling
 
 Upon receiving a command packet from the GDB client, the command must be handled and the appropriate response delivered.
 Each command packet class implements a `handle()` member function. This function is called upon receipt of the command

+client, as well as other debug session specific information. The `TargetControllerConsole` object provides an interface
