settings object
This method will free all resources allocated for the settings object.
bool close()
Parameters:
None.
Return value:
true on success, false on failure.
Remarks:
If the close method is not called explicitly, the object will automatically free itself when the object goes out of scope or when the engine shuts down.
Example:

    // Store a value in the registry and explicitly close afterwards.

    void main()
    {
    settings game_data;
    bool success=game_data.setup("Testtime Interactive", "Bonebreaker", false);
    if(!success)
    {
    alert("Error", "Could not access the registry.");
    exit();
    }
    game_data.write_number("music_volume", -5.0);
    game_data.close();
    }
