Compute weighted in-, out-, and total-degree for random derived networks

[kdahlquist]

Instead of using Gephi to compute weigted degree stats, we can easily do it in Excel by summing across the rows and columns of the "network_optimized_weights" sheet. This is priority 0.5.

In Excel we can also compute the average, median, max, min of weights across the rows and columns to get the descriptive stats for all incoming and outgoing edges for a gene.

@khorstmann has completed this for random networks 1-20. She needs to complete 21-31. Also, these data need to be compiled into a single spreadsheet to facilitate comparison across networks.

This was covered by #325, so closing this one, too.
