Any thoughts on having an option like
EIGEN_INITIALIZE_MATRICES_BY_ZERO called
EIGEN_INITIALIZE_MATRICES_BY_NAN which does what it suggests? It'd be
handy for tracking down algorithmic problems due to uninitialized data
being used. Only hiccups I can see would be initializing the real-
and imaginary portion when NumTraits<Scalar>::IsComplex holds and/or
using numeric_limits<NumTraits<Scalar>::Real>::has_quiet_NaN to
determine when it could be performed at all.
