Changed StringT::versioncmp because different platforms show different
behavior with EOF's with istrstream's. FYI, SGI and GNU do not hit the
EOF even if it is the terminator for the final integer (and probably
any other type ending with a delimiter), while DEC and Metrowerks do.

Added support of output of element, rather than nodal, variables from
ElasticT, DiffusionT, CSEAnisoT, and CSEIsoT. The input files newer than
v3.01 must contain flags specifying the output of element output variables.
Output of element variables is not yet supported for parallel execution.

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
