Comment:
oops ! Sorry for that `:-)`
It turns out that changing this method was not a good idea though.
Avoiding to use the C++ class was intended as a way to save on unseless
computations, but it looks like the Coin library transforms the arrays
into the same structure immediately when called, so everything is done
twice, so I removed that part `:-)`
By the way, do you know what is the difference between sage_free and free,
or between sage_malloc and malloc ? I always wondered `:-)`
