Support Multi-value Return

Somehow

Perhaps using a new datatype:

LuaMultivalue

So we have LuaFunction< LuaMultivalue() >

and LuaMultiValue has
.Count()
.Get(int idx)

Also we can pass it in too: LuaFunction< void(LuaMultivalue) > for variadic.

and LuaMultiValue will have
.Add()
.Remove()

But what about assigning LuaMultivalue to a table? All operations on data will not be closed on all primitive types.

Unless LuaMultivalue simple turns into a LuaTable, but that would introduce inconsistency.

This is troublesome.
