KLU solver

[jonrkarr]

As of version 2.6 the CVODES solver by SUNDIALS supports the sparse linear solver KLU from SuiteSparse (http://faculty.cse.tamu.edu/davis/suitesparse.html). Especially for large scale systems with sparse interactions it is important to specify this as linear solver as it will typically yield a substantial computational speedup.

I am not sure whether "algorithm characteristic" is correct. It should be treated the same as other linear solvers such as GMRES.

name: KLU ("Clark Kent" LU factorization algorithm)
type: algorithm characteristic
short description: sparse left-looking LU factorization, using a block triangular form

Thank you for the term suggestion!
I have added KLU as an algorithm (KISAO_0000497). It is available since version 2.3.12.
