|
Scans regionsets for TileEntities and Entities, filters them, and writes out
|
|
POI/marker info.
|
|
|
|
A markerSet is list of POIs to display on a tileset. It has a display name,
|
|
and a group name.
|
|
|
|
markersDB.js holds a list of POIs in each group
|
|
markers.js holds a list of which markerSets are attached to each tileSet
