This template is intended to be used to allow a single reference source for map objects. This template is still being actively worked on ans is as yet undocumented. If in doubt, don't use it yet.
By default the generated map is 512x1024 pixels, at zoom level 2
The reason this template is required is that passing templates into extensions requires use of the #tag: function. In practice this template can probably be simplified somewhat
- contentonly - The important part of this template. If contentonly=yes then only the first parameter (the map data lines) will be returned from the template. This allows condmaps to be nested so that multiple maps can be merged
