  adding non-strict DR-bar convergence tester

This convergence tester is non-strict in the sense, that it returns
true if the precision goal or the maximum number of iterations has
been reached.  If this convergence tester is used, no exception of
type NoConvergenceError() is thrown and the non-convergence is
therefore not treated as an error case.

However, non-convergent points are of course a problem!  Therefore, a
warning will be added to catch such problematic cases.

  Log Message:
  -----------
  implement non-convergence warning

Now we have two kinds of non-convergence issues: errors and warnings.
This distinction allows for a non-strict convergence criterion.

flag_no_convergence_error() is called if the two-scale solver throws
an exception of type NoConvergenceError .  In this case we interpret
the non-convergence issue as a real problem, where the spectrum cannot
be trusted.  Whether the two-scale solver throws an exception or not
depends on the convergence tester.

flag_no_convergence_warning() is called in the non-strict convergence
tester, if the maximum number of iterations has been reached, but the
precision goal has not been reached yet.  The non-strict convergence
tester therefore allows to be less strict about the interpretation of
the non-convergence issue: A non-convergence warning means, please be
careful with the spectrum!
