* class CGlobalConsoleTaskList
*
* PURPOSE: A global console task list that provides unique IDs for all console tasks
* When a task is instantiated, its constructor registers in the global task list,
* and obtains a globally unique ID. This ID is unique for the process and should
* not be persisted.
* The destructor of the task removes it from this list.
*
* USAGE: Call CGlobalConsoleTaskList::GetConsoleTask to obtain a pointer to the task
* that has a specified ID.
* Call CConsoleTask::GetUniqueID to get the unique ID for a task.
*
* Thus, CGlobalConsoleTaskList::GetConsoleTask(pConsoleTask->GetUniqueID()) == pConsoleTask
* is always true.
