+-- CommandState.lua
+
+-- Implements the cCommandState class representing a command state for each VIP player
+
+--[[
+The command state holds internal info, such as the coords they selected using the wand
+The command state needs to be held in a per-entity manner, so that we can support multiple logins
+from the same account (just for the fun of it)
+The OOP class implementation follows the PiL 16.1
+
+Also, a global table g_CommandStates is the map of PlayerEntityID -> cCommandState
