Creating a simple map

The first map we create should be the road map we created in GeoServer. We have to set up a blank map and load a WMS layer in it. Once it's working, we can bind the map to the appropriate button:

1. Create a new map with the L.map function and save it to a variable. It needs the ID of the container element as a string, while it can additionally accept other parameters bundled in an object. For now, let's provide a center and a zoom parameter. The center is an array of two WGS 84 coordinates (latitude and longitude), while the zoom is a positive integer. Supply center coordinates that fit our map. We can get them either from QGIS or from Google Maps by centering the map on our study area and noting down the coordinates ...
