Title: Add row and col fields to nodes.

It can be helpful for a node to know its row and column, for example, to look up information specific to that row or column, for use in a tooltip, creation of a URL in a tooltip, etc.

This mod adds those fields. I'm assuming the additional CPU overhead and required memory storage will not be significant.
