/**
  \interface DebugCmdInterface debug.h <rts/debug.h>
  
  \brief Debug command group interface.

  A debug command group interface implementation defines a new
  command group and the commands implemented for this group.

  A Debug command group interface instance must register itself
  using Debug::AddCommands. Ownership is then transfered to
  the Debug module unless the object is manually removed
  by calling Debug::RemoveCommands.

  For convenience the macro \ref DEBUG_CREATE_COMMAND_GROUP
  can be used as well.
