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.
