\file CommandDirectory.h
\brief Contains declarations for CommandDirectory class
\class CommandDirectory
\brief Allows registration and lookup (by name) of command types.
A singleton. This fulfills a similar purpose to CommandManager, but for general
Commands rather than menu items. Eventually they could be unified but for now
they are kept separate to make things simpler.
