convergence then zoning failures

[gary]

the following has convergence failures and eventually aborts due to dr too small

The test case runs to a finish on the mainline at r2696, most likely thanks to the new electron temperature and density solvers that were ported to the mainline in r2539. There are still quite a few convergence problems though, and especially the second temperature failure looks bad (it took nearly 10,000 iterations to fail!).

The test case crashes on c08_branch at r2696 due to a failed assert on atom_level3.cpp:381.
