+Calling a Lua function is done internally by pushing the function using PushFunction(), then pushing the

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
