RegionPager can now be instanciated with template parameters

* Fixed Region::GetX() and Region::GetY()
* Replaced calls to std::find_if with regular for loops
* Changed typing of RegionPager::regionList
** regionList now holds pointers rather than the objects themselves
* Added vestigial classes MapFileFormat and MapGenerator
** MapGenerator creates and destroys the region objects
* I'm leaving in the debugging code for now
** This includes trace statements and a basterdized main() function in
