token_(symbol)_weights to normalized weights

[AngelaKTE]

Refactor "token_(symbol)_weight" to normalized weights:

The white paper defines it in terms of the normalized weights (such that the sum of all normalized weights is 1) - so 0.8 and 0.2 in that case.

As for the why, it's not explicitly stated in the white paper, but from eq 10 in this proof we see that Wn must be a number between 0 and 1 (since 0<Vn<V by definition).

So i add token_(symbol)denorm and token(symbol)_weight from 0 to 1

Wait - no need to touch token_(symbol)_denorm.

Just change token_(symbol)_weight as outlined (0 to 1).

Done
