1. Add default boundary constraint(no constraint) and initial guess to the dictionary
...
2. With the boundary constraint of exponential term, now non-quadratic yield criteria (isotropic Barlat 1991, anisotropic Barlar 1991, Hosford) take effect.

1. Replace curve_fit(see minpack.py) with curve_fit_bound(see damask/util.py), now the boundary constraint can be applied.

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.
