sfepy/sfepy — Issue #22: iterative sparse linear solvers

Using a direct sparse linear solver (umfpack) is very convenient as it can
solve any nonsingular system very quickly. If the LU-decomposed matrix fits
into memory, that is.

-> Iterative solvers are needed. First, let us try PETSc, via petsc4py.

Revision 65(341c69bf86f3) partially solved this, as all iterative solvers of Scipy
are now accessible. The next step is Petsc.

Revision 170(8544e03cb008) made PyAMG solvers accessible. Shall we close this? PETSc
can wait.

Let's close it.
