Calculate edge-weighted closeness, a weighted version of closeness(sna).

ewc(vnetwork)
``` |

`vnetwork` |
A valued adjacency matrix. Must be weakly connected. |

The EWC is defined as:
*EWC(i)=\frac{∑_{j}{\frac{llv(i,j)}{d(i,j)}}}{\max(lv)(n-1)}*,
where
*llv(i,j)* is the average last line value on the path from node *i* to node *j*,
*d(i,j)* is the distance from *i* to *j* and
*\max(lv)* is the maximum of all line values in `vnetwork`

.

A vector of length `dim(vnetwork)[1]`

containing the EWC values.
