TestSystem

 Calculate the  the performance index and the output of a fuzzy system.

 function [PI,xd]=TestSystem(fis,TI,TIOld,OutTest,params,PerformanceIndexType)

 Calculate the  the performance index and the output of a fuzzy system 
 for a sample data set.

 TIold   - cell array containing the observations in "old style" structures
           obsold - the old-style structure describing the observation
           obsold(i)--name
