Switch numerical scaling to relative

[cdiener]

Now uses relative scaling, ergo bound * a where a >> 1 instead of just assigning a very large bound. This should maintain a bound structure that is more similar to the original model and lead to less blocked reactions in the reconstruction.

Still requires validation.
