26//! The GameLoader
27/**
28 *  The game loader loads all game date. this is performed in the following way:
29 * 1. Read the structure of campaings and worlds
30 * 2. Create the instances of the tree: here _ALL_ StoryEntities are created
31 *    also if they are not yet used. the worlds should load their data in
32 *    the StoryEntity::load() and StoryEntity::init() functions! NOWHERE ELSE!
33 *    Elsewhere, all the data will be allocated at the beginning... mess...
34 * 3. StoryEntities are load() and init() before they start
35 * 4. once the gamloader starts the game there will be a campaing starting a
36 *    world. this is done by callaing those StoryEntity::start()
