function params=addterminals(params,varargin)
%ADDTERMINALS    Stores additional terminals info as parameters for GPLAB.
%   ADDTERMINALS(PARAMS,TERMNAME) returns updated parameter
%   variables where the terminals information (name - arity
%   is always null) has been added with the data provided in the
%   function arguments TERMNAME. Several terminals can be added
%   at the same time by adding several TERMNAME arguments.
%
%   Input arguments:
%      PARAMS - the algorithm running parameters (struct)
%      TERMNAME - the name of the terminal to use (string)
%      ...
%   Output arguments:
%      PARAMS - the updated algorithm running parameters (struct)
