/*********************************

* Takes an XML `.osm` file and converts it into a cucumber scenario definition like

|
* Given the node locations
|
|
* | node | lon | lat |
|
|
* .....
|
|
* Given the ways
|
|
* | nodes | tag1 | tag2 | tag3 |
|
|
* .....
|
|
*
|
|
* Note that cucumber tests are limited to 26 nodes (labelled a-z), so
|
|
* you'll need to use pretty small OSM extracts to get this to work.
