Updates to make compatible with the the changes to IsotropicT

Added QuadLog isotropic materials formulated in principal stretches
in both 2D and 3D to verify the underlying machinery in OgdenIsotropicT

Young's modulus, Poisson's ratio, the shear modulus, the bulk modulus,
and the Lame constant lambda are now calculated and stored after any
are set using
IsotropicT(ifstreamT& in);
void Set_E_nu(double E, double nu);
void Set_mu_kappa(double mu, double kappa);
and can be accessed using
double Young(void) const;
double Poisson(void) const;
double Mu(void) const;
double Kappa(void) const;
double Lambda(void) const;

Added static bool CompatibleOutput(const ContinuumMaterialT&, const ContinuumMaterialT&) which returns true if the two materials has the same number and sequence of material output parameters.

The current input file version has changed to v3.02 because of
changes to the element input. For allowing writing in some "backward
compatibility", the input file version is how available from FEManagerT
using
const StringT& Version(void) const
Version strings can be compared using StringT::versioncmp

added
const dMatrixT& SpectralDecompT::Eigenmatrix(void) const
for access to the matrix of eigenvectors as columns of the
return matrix

added a flush of cout for SGI because the prompt for input where not
appearing. The prompts in cout still do not always appear for SGI.mpi

added error messages when trying to OpenRead, OpenWrite, or Create
ExodusII when ACCESS in not available. The constructor and de-
structor do not require ACCESS.

added StringT::versioncmp to do comparisons of verions numbers

transposed the matrix of eigenvectors so that the vectors are returned
in columns rather than rows
