1. Change yieldStress from 'list' to 'numpy.arrary', thanks to Martin's suggestion (3907);
...
2. Change '3*3' Cauchy stress tensor to '1*6', now the number of input 'xdata' for fitting is 6*Points, which is less than the former 9*Points.

Fix the bug of calculating principal stresses. Now the fitting result is better for the criteria which expressed in principal stresses.
...
Thanks to Martin.
