1. In Workbench, create .ega file for SVM classification - using data: http://dione.zcu.cz/~toman40/encog/data7.zip - and set "Maximum Error Percent (0-100)" = 10.
2. Excecute "task-full" -> the training will end up performing only 1 iteration, with "Training Error" = 0.000000 % (wrong).
3. Run SVM Search Training again and set Gamma = 0.005-0.01 step 0.001 and C = 0.01-0.05 step 0.01 -> the training will end up with "Training error" = 6.68 %, but there is only ~60 % of correctly classified rows in ``data7_output.csv`` (where ``y``=``Output:y``); after executing task-evaluate.
