* Changed names of functions node_fromlink_index, and node_tolink_index.
* Changed names of functions node_fromlink_index, and node_tolink_index.

== Changed ==

* Function name changes:
  - node_fromlink_index is now outlink_index_at_node
  - node_tolink_index is now inlink_index_at_node
  Both functions return link ids for each node of a structured quad grid.
  This is essentially (exactly?) the inlink and outlink matrices of
  RasterModelGrid.
