-// LuaState.h
-
-// Declares the cLuaState class representing the wrapper over lua_State *, provides associated helper functions
-
-/*
-The contained lua_State can be either owned or attached.
-Owned lua_State is created by calling Create() and the cLuaState automatically closes the state
-Or, lua_State can be attached by calling Attach(), the cLuaState doesn't close such a state
-Attaching a state will automatically close an owned state.
-
-Calling a Lua function is done by pushing the function, either by PushFunction() or PushFunctionFromRegistry(),
-then pushing the arguments (PushString(), PushNumber(), PushUserData() etc.) and finally
-executing CallFunction(). cLuaState automatically keeps track of the number of arguments and the name of the
-function (for logging purposes), which makes the call less error-prone.
-
-Reference management is provided by the cLuaState::cRef class. This is used when you need to hold a reference to
-any Lua object across several function calls; usually this is used for callbacks. The class is RAII-like, with
-automatic resource management.
