Detailed Description

This class is responsible for managing all levels and the lua backend, it is the heart of the engine.

MOCK: contained in game_manager_mock.hpp This is a mock class of the game_manager. It contains the exact same function definitions as the real game_manager, but not the implementations. This is need to properly test the lua_backend. GMock is not used as it requires to use virtual methods (interfaces) to create mocks. We assume that this mock contains the same definitions as the real thing, but this is not checked anywhere and is done per hand. (A compile time error will occur if a method/attribute is not found, but things like wrong data types in the method arguments may not be noticed easily).
