-//
-// LuaWrapper is a library designed to help bridge the gab between Lua and
-// C++. It is designed to be small (a single header file), simple, fast,
-// and typesafe. It has no external dependencies, and does not need to be
-// precompiled; the header can simply be dropped into a project and used
-// immediately. It even supports class inheritance to a certain degree. Objects
-// can be created in either Lua or C++, and passed back and forth.
-//
-// The main functions of interest are the following:
-//  luaW_is<T>
-//  luaW_to<T>
-//  luaW_check<T>
-//  luaW_push<T>
-//  luaW_register<T>
-//  luaW_setfuncs<T>
-//  luaW_extend<T, U>
-//  luaW_hold<T>
-//  luaW_release<T>
-//
-// These functions allow you to manipulate arbitrary classes just like you
-// would the primitive types (e.g. numbers or strings). If you are familiar
-// with the normal Lua API the behavior of these functions should be very
-// intuative.
-//

-// to call the new function on your class table. You will need to manually push
-// objects from C++. By default, the default constructor is used to create

-//
-// By default LuaWrapper uses the address of C++ object to identify unique
-// objects. In some cases this is not desired, such as in the case of
-// shared_ptrs. Two shared_ptrs may themselves have unique locations in memory
-// but still represent the same object. For cases like that, you may specify an

-// object on to the stack.
-//
-// luaW_register will set table as the new value of the global of the given
-// name. luaW_setfuncs is identical to luaW_register, but it does not set the
-// table globally.  As with luaL_register and luaL_setfuncs, both funcstions
-// leave the new table on the top of the stack.

-// A set of trivial getter and setter templates. These templates are designed
-// to call trivial getters or setters.
-//
-// There are four forms:
-//  1. Getting or setting a public member variable that is of a primitive type
-//  2. Getting or setting a public member variable that is a pointer to an
-//     object
-//  3. Getting or setting a private member variable that is of a primitive type
-//     through a getter or setter
-//  3. Getting or setting a private member variable that is is a pointer to an
-//     object through a getter or setter
-//
-// The interface to all of them is the same however. In addition to plain
-// getter and setter functions, there is a getset which does both - if an
-// argument is supplied it attempts to set the value, and in either case it
-// returns the value. In your lua table declaration in C++ rather than write
-// individiual wrappers for each getter and setter you may do the following:
-//
-// static luaL_reg Foo_metatable[] =
-// {
-//     { "GetBar", luaU_get<Foo, bool, &Widget::GetBar> },
-//     { "SetBar", luaU_set<Foo, bool, &Widget::SetBar> },
-//     { "Bar", luaU_getset<Foo, bool, &Widget::GetBar, &Widget::SetBar> },
-//     { NULL, NULL }
-// }
-//
-// Getters and setters must have one of the following signatures:
-//    void T::Setter(U value);
-//    void T::Setter(U* value);
-//    void T::Setter(const U& value);
-//    U Getter() const;
-//    U* Getter() const;
-//
-// In this example, the variable Foo::bar is private and so it is accessed
-// through getter and setter functions. If Foo::bar were public, it could be
-// accessed directly, like so:
-//
-// static luaL_reg Foo_metatable[] =
-// {
-//     { "GetBar", luaU_get<Foo, bool, &Widget::bar> },
-//     { "SetBar", luaU_set<Foo, bool, &Widget::bar> },
-//     { "Bar", luaU_getset<Foo, bool, &Widget::bar> },
-// }
-//
-// In a Lua script, you can now use foo:GetBar(), foo:SetBar() and foo:Bar()

-// luaU_func is a special macro that expands into a simple function wrapper.
-// Unlike the getter setters above, you merely need to name the function you
-// would like to wrap.
-//
-// For example,
-//
-// struct Foo
-// {
-//     int DoSomething(int, const char*);
-// };
-//
-// static luaL_reg Foo_metatable[] =
-// {
-//     { "DoSomething", luaU_func(&Foo::DoSomething) },
-//     { NULL, NULL }
-// }
-//
-// This macro will expand based on the function signature of Foo::DoSomething
-// In this example, it would expand into the following wrapper:
-//
-//     luaU_push(luaW_check<T>(L, 1)->DoSomething(luaU_check<int>(L, 2), luaU_check<const char*>(L, 3)));
-//     return 1;
-//
-// In this example there is only one member function called DoSomething. In some 
-// cases there may be multiple overrides for a function. For those cases, an 
-// additional macro has been provided, luaU_funcsig, which takes the entire
-// function signature. The arguments to the macro reflect the order they would
-// appear in the function signature: return type, type name, function name, and
-// finally a list of all the argument types. For example:
-//
-// struct Foo
-// {
-//     int DoSomething (const char*);
-//     int DoSomething (const char*, int);
-// };
-//
-// const struct luaL_Reg Foo_metatable[] =
-// {
-//     {"DoSomething1", luaU_funcsig(int, Foo, DoSomething, const char*)) },
-//     {"DoSomething1", luaU_funcsig(int, Foo, DoSomething, const char*, int)) },
-//     { NULL, NULL }
-// };
-//
-// These macros and it's underlying templates are somewhat experimental and some
-// refinements are probably needed.  There are cases where it does not
-// currently work and I expect some changes can be made to refine its behavior.
