An incompressible, isotropic, hyperelastic material law with a polynomial form
W(I_1,I_2) = Sigma_{0<p+q<=N} alpha_{pq} (I_1-3)^p (I_2-3)^q - (pressure/2) C^{-1}
For example, if N=1, this reduces to the Mooney Rivlin law W(I_1,I_2) = alpha_{10} (I_1-3) + alpha_{01} (I_2-3) - (pressure/2) C^{-1} ie the matrix alpha has the form [ 0 c1 ] [ c2 0 ] where c1 and c2 is the usual notation for the Mooney-Rivlin constants
The polynomial is specified by passing in N and the matrix (actually a std::vector of std::vector<double>s) alpha. alpha should be of size N+1 by N+1, with the bottom right hand block (ie the components such that p+q>N) all zero. alpha[0][0] should really also be 0, but, being since alpha[0][0] (I1_3)^0 (I2-3)^0 is a constant and disappears when the strain energy W is differentiated to obtain the stress, it is not used. An exception is thrown if alpha[p][q]!=0 for p+q > N though.
