use eigen stableNorm() instead of cminpack 'enorm'. The results are mostly

slightly better in tests (one test needs 15 iterations intead of 16, for
the same result). Some numerical results have improved slightly, too.
If one uses blueNorm() instead, an assert for 'overflow' is raised from
blueNorm()

add another (actuallY) difficult NIST test : BoxBOD.

The first try fails, the second one passes, but with a very bad accuracy
(~4 digits only).
anyway, my aim is to check we do not change cminpack while portint, so i
keep this test.

Add all other file from cminpack/examples as tests.

Important : one test was failing because cminpack-1.0.2 does x[3]=1. on x
which is of size 3. Probably because fortran indices are shifted wrt to C
indices and someone forgot to fix this one.
This is correct in this commit and this is the only change I've done on files
from cminpack examples.
(i've also reported the bug to cminpack author)
