+This is the main Class to manage loading and unloading of maps, line of sight, height calculation and so on.
+For each map or map tile to load it reads a directory file that contains the ModelContainer files used by this map or map tile.
+Each global map or instance has its own dynamic BSP-Tree.
+The loaded ModelContainers are included in one of these BSP-Trees.
+Additionally a table to match map ids and map names is used.
