Function getProjection

getProjection(): JProjection
JMap.Project.getProjection

Returns loaded JMap project projection.

In the map, the projection is always "EPSG:3857", but that function returns the project defined projection (so it can be different than ESPG:3857).

Returns JProjection
Throws
If no project is loaded

Example
```
// returns the project projection
JMap.Project.getProjection()
```
