Code for computing the `Weighted feedback arc` and `Weighted reversing join` metrics

[AndreaGuarracino]

To be super sure to compute the same values, could you please share the code you've used to compute the following metrics?

• Weighted feedback arc (WFA) – the sum of weights of all feedback arcs, i.e. backward pointing edges
• Weighted reversing join (WRJ) – the sum of weights of all reversing joins, i.e. edges joining two in- or two out-sides.

Here is the code for computing the weighted feedback arc and weighted reversing join metrics.

Very kind, thank you.
