+-- PlayerAreas.lua
+-- Implements the cPlayerAreas class representing the per-player area storage object
+
+--[[
+Each player instance is expected to have a separate object of type cPlayerAreas.
+Each object has an array of {cuboid, IsAllowed} tables, one for each area that is "within reach"
+The code can then ask each object, whether the player can interact with a certain block or not.
+A player can interact with a block if either one of these is true:
+1, There are no areas covering the block
+2, There is at least one area covering the block with IsAllowed set to true
+The OOP class implementation follows the PiL 16.1
+
+Also, a global table g_PlayerAreas is the actual map of PlayerName -> cPlayerAreas
