not much done. don't remember anyways
By2 is discarded (implicitly set to 0)
started to work on adjoint solver
started adding Adjoint Solver. ALSO, in original solver, initial vector of particular solution is chaged -- see comments in code.
more work on adjSolver is done
adoint solver computes something
polishing adjoint. looking to fix the precision. changed initial time step number
looking for errors
