// SqPlus.h
// Created by John Schultz 9/05/05, major update 10/05/05.
// Template function call design from LuaPlusCD by Joshua C. Jensen,
// inspired by luabind which was inspired by boost::python.
// Const argument, const member functions, and Mac OS-X changes by Simon Michelmore.
// DECLARE_INSTANCE_TYPE_NAME changes by Ben (Project5) from http://www.squirrel-lang.org/forums/.
// Added Kamaitati's changes 5/28/06.
// Free for any use.
