OsmHistoryReader (JOSM)

java.lang.Object
- org.openstreetmap.josm.io.OsmHistoryReader

```
public class OsmHistoryReader
extends java.lang.Object
```
Parser for OSM history data. It is slightly different from OsmReader because we don't build an internal graph of OsmPrimitives. We use objects derived from HistoryOsmPrimitive instead and we keep the data in a dedicated HistoryDataSet.
