Computes the S_{14} similarity index between two network matrices.

1	s14(d1, d2)

`d1`	An n by n matrix representing a network.
`d2`	An n by n matrix representing a network.

Given two networks of interest, a common measure of similarity is the S_{14} index introduced by Gower and Lagendre (1986). The function s14 computes this similarity measure for two networks having the same dimensions.
