#pragma once

// Forward class declarations aren't enough here. The compiler
// generated CMapInfo d-tor, generates the unique_ptr d-tor as well here
// as a inline method. The unique_ptr d-tor requires a complete type. Defining
// the CMapInfo d-tor to let the compiler add the d-tor stuff in the .cpp file
// would work with one exception. It prevents the generation of the move
// constructor which is needed. (Writing such a c-tor is nasty.) With the
// new c++11 keyword "default" for constructors this problem could be solved. But it isn't
// available for Visual Studio for now. (Empty d-tor in .cpp would be required anyway)
