MATESSL = "essl" - A matrix type providing direct solvers (LU) for sequential matrices via the external package ESSL. If ESSL is installed (see the manual for
instructions on how to declare the existence of external packages),
a matrix type can be constructed which invokes ESSL solvers.
After calling MatCreate(...,A), simply call MatSetType(A,MATESSL).
This matrix type is only supported for double precision real.
This matrix inherits from MATSEQAIJ. As a result, MatSeqAIJSetPreallocation is
supported for this matrix type. One can also call MatConvert for an inplace conversion to or from
the MATSEQAIJ type without data copy.

-mat_type essl -sets the matrix type to "essl" during a call to MatSetFromOptions()
