        public int add(int type,
               int level,
               int timeout)
        Add a resource to the CustomParams instance for boosting. If a resource of the same type already exists, it is overwritten.
        To run the boost, use start(CustomParams).
        Parameters:
        type - Resource type field.
        level - Level to set for the resource type.
        timeout - Duration to boost after this module is called, in milliseconds.
        Returns:
        0: success -1: fail
