GeoJSON enforces strict JSON
----------------------------
  GeoJSON produces and consumes only strict JSON.
  NaN and Infinity are not permissible values according to the JSON specification.

  >>> import geojson
  >>> geojson.dumps({"type": "Point", "coordinates": [float("nan"), 1.0]}) # doctest: +ELLIPSIS
  Traceback (most recent call last):
              ...
  ValueError:...not JSON compliant...

  
  >>> geojson.dumps({"type": "Point", "coordinates": [float("nan"), 1.0]}) # doctest: +ELLIPSIS
  Traceback (most recent call last):
              ...
  ValueError:...not JSON compliant...

  >>> json = '{"type": "Point", "coordinates": [1.0, NaN]}'
  >>> geojson.loads(json) # doctest: +ELLIPSIS
  Traceback (most recent call last):
              ...
  ValueError:...not JSON compliant...

  >>> json = '{"type": "Point", "coordinates": [Infinity, -Infinity]}'
  >>> geojson.loads(json) # doctest: +ELLIPSIS
