    \brief Definition of the SoundEngine

    !!AVOID!!:
    SDL_OpenAudio
     Use Mix_OpenAudio instead. 
    SDL_CloseAudio
     Use Mix_CloseAudio instead. 
    SDL_PauseAudio
     Use Mix_Pause(-1) and Mix_PauseMusic instead, to pause.
     Use Mix_Resume(-1) and Mix_ResumeMusic instead, to unpause. 
    SDL_LockAudio
     This is just not needed since SDL_mixer handles this for you.
     Using it may cause problems as well. 
    SDL_UnlockAudio
     This is just not needed since SDL_mixer handles this for you.
     Using it may cause problems as well.
