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)

big refactoring in Product.h:
...
- all specialized products now inherits ProductBase
- the default product evaluated by Assign is still here,
but it is currently enabled for small fixed sizes only
- => this significantly speed up compilation for large matrices
- I left the OuterProduct specialization empty as an exercise...

we never assert on conditions that depend on the result of a computation!!
also the assertion that rank>0 amounts to matrix!=0 which we have to leave under the responsibility of the user.
