  This test returns NOX::StatusTest::Failed if the norm of a vector is

  NOX::StatusTest::Unconverged.  The user can specify whether to use
  the F vector or the solution vector from the current solution group
  for the check.  NOX does not have access to vector entries so the
  number used in the NaN/Inf check is based on the norm of a vector.

  NOX::StatusTest::None, then the status is set to
  NOX::Status::Unevaluated and returned.

  /*! \brief The finite number test algorithm.

    Autoconf will test to see if the compiler implements the isnan()
    and isinf() functions in the cmath or math.h headers.  If so, we
    will use these.  If not, we supply a default implementation. The
    default implementation is only guaranteed to work if the code is
    IEEE 748/754 compliant.  The checks for isnan and isinf are
    separate because compilers like the old sgi platforms support one
    but not the other.  See bug 2019 for more details.

    This method is public so that other objects (solvers, line
    searches, and directions) can use this test on their own values.

    Return Values:
    - 0 = Finite Number
    - -1 = NaN
    - -2 = Inf
