+Use the addon's private table as an isolated environment.
+By using { __index = _G } metatable we're allowing all global lookups to transparently fallback to the game-wide
+globals table, while the private table itself will act as a thin layer on top of the game-wide globals table,
+allowing us to have our own global variables isolated from the rest of the game.
+
+This accomplishes several goals:
+1. Prevents addon-specific "globals" from leaking to game-wide global namespace _G
+2. Optionally retains the ability to access these "globals" via the only exposed global variable "VoiceOver"
+3. Allows us to make overrides for WoW API's global funtions and variables without actually touching
+   the real global namespace, making these overrides visible only to this addon.
+   This will be useful mainly for adding backwards-compatibility with older WoW clients.
+
+setfenv(1, VoiceOver) must be added to every .lua file to allow it to work within this environment,
+and this Environment file must be loaded before all others
