Fix issue #38 at last!

Unfortunately this has introduced a loss of efficiency.
Between commit da73630 and commit 6feec93, we see more than 10% loss. This has been tested on Bertrand's optimizer04 as follows:
./optimizer04 ../plugins/optim/benchs/coconutbenchmark-library2/hs099.nl acidhc4 compo lsmearmg bs 1 1.e-7 1.e-6 7200 1
with the initial domain restricted as follows
double _sol[]={0.541993 , 0.530903 , 0.508103 , 0.480116 , 0.451103 , 0.409231 , 0.35281 , -1939.93 , -7908.68 , -18412.6 , -20003.9 , -17422.7 , 20342.1 , -155.195 , -322.304 , -97.854 , 34.2024 , 69.0438 , 770.176 }; Vector sol(19,_sol); sys->box = sol + Interval(-1,1)*abs(sol);
Output is:

Time with da73630 is around 21.3s. Time with 6feec93 is around 19.3s.
The new version however makes use of vector instead of raw arrays.
Sorry, something went wrong.
