Failure to handle high spin nuclei

[wbittner100]

CluE currently is unable to handle high spin nuclei due to hard coded limitation and O(I^n) memory pre allocation for spin operators where I is the spin multiplicity and n is the maximum cluster size.

parseNuclei.m lines 436 to 492, does not handle spin multiplicity greater than 3

generateSpinOperators.m line 35, matrix becomes too large under high spin. For example with a spin multiplicity of 8 and max cluster size of 2 the matrix becomes 8^2 x 8^2 x (number of spin operators) large.
