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.
...
2. Transfer the output information into dictionary 'fittingCriteria', compact subroutine 'fit'.

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.
