sol2/sol/object.hpp
ThePhD 88155d44e0 sol::property is implemented for usertypes now
sol::this_state is  a transparent argument that gets the current state at any position in any callback
sol::variadic_args allows a person to get something that can reference the "rest of the arguments", though it doesn't enforce that it has to be the last argument

Closes #57
Closes #59
Closes #60
