        @remarks
                Class for handling OIS exceptions. Much cleaner than checking every method for reurn value.
                Inherits from std::exception so you can simply log those messages if you want to be generic.
                Also note that this has a source file now since OSX was not finding the OIS::Exception symbol
                which would cause program abortion with now correponding exception type.
