/**
|
|
* This component shows a map which focuses on a single OSM-Way (linestring) feature.
|
|
* Clicking the map will add a new 'scissor' point, projected on the linestring (and possible snapped to an already existing node within the linestring;
|
|
* clicking this point again will remove it.
|
|
* The bound 'value' will contain the location of these projected points.
|
|
* Points are not coalesced with already existing nodes within the way; it is up to the code actually splitting the way to decide to reuse an existing point or not
|
|
*
|
|
* This component is _not_ responsible for the rest of the flow, e.g. the confirm button
