This is a map component based on [OpenLayers](https://openlayers.org/) to show different types and layers of maps from sources like OpenStreet, Bing, SwissTopo ary WMTS/WMS compatible source with some features like markes or shape drawing. The component has implemented the swiss specific coordination projection (VL03/VL95) and therefore can project map content from swisstopo (https://map.geo.admin.ch/).

## Major Changes

Starting fromn version 1.5, the coordinates are represented and defined according to EPSG. This means the input for a Coordinate object will be switched: Coordinate(1197650, 2604200) > Coordinate(2604200, 1197650) or new Coordinate(51, 0) > Coordinate(0, 51)
