  1. + New: A class PreconditionLU which + provides a wrapper to the complete LU decomposition + preconditioner of PETSc. Furthermore a class + SolverPreOnly was implemented. It + is a wrapper for the PETSc solver type KSPPREONLY, which + only applies the preconditioner. In conjunction with + PreconditionLU this provides a + simple direct solver, which could be used for small to medium + sized problems on a single processor machine. +

  2. New: A class PointerComparison for comparing pointers that may or may not be of the same type.
