Generates fuzzy rules of fuzzy inference system (FIS) using CART algorithm and ANFIS training

checkfisx(fis)
function res = checkfisx(fis)
%CHECKFISX Checks the fuzzy inference system properties for legal values.
%
%   See checkfis for syntax and explanation.
% 
%   It is completely based on MATLAB's checkfis 
%   with some modifications, so it's compatible
%   with extendent fuzzy rule structure.
% 
%   Compare also code of this function
%   with code of the original checkfis.
