GameManager

The GameManager class is the core class of the engine: it controls the main execution loop, handles file loading, input reading, and command execution. Apart from this, it has some methods for game-level manipulation, apart from methods for accessing the various areas that compose a game.

The interface for this class is:

• static GameManager* getInstance(): returns the unique instance of the GameManager, implemented with the Singleton pattern.

• void erase(): clears ALL the game objects.

• void loadXML(const std::string& filename): loads a certain game file into the proper game objects.

• void startGame(): starts the game main loop.

• Area* getArea(std::string name): returns the Area item with the given name.

• void setEndGame(bool end): sets the end game internal value to the given value.

• const std::string& getCurrentLocation(): gets the player's current location.
