[Tagging] hiking route from= and to= tags

[Peter Elderson]

Labeled nodes, interconnected through routes (chains of ways). The nodes
refer to each other, and in between nodes you only need a single pointing
symbol for all the network (the well known yellow diamond). That is a node
network. Apart from the node list no guideposts are needed.

The function is not to route someone from A to B in the shortest or fastest
way, but to plan recreational trips using predesigned connections
designated/selected for this purpose by the network operator, resulting in
a simple list of nodes (names, numbers or even colours) to follow, with the
yellow diamond always guiding you to the next one.

It is true that a routing/navigating application could theoretically
achieve much the same effect if a number of conditions are met, but the
main use is on recreational routes where routing and navigating is
impractical or not (yet) in general use, even frowned upon (e.g. hiking,
canoeing, horse riding, inline skating).
