 DataSource is a wrapper for the OGR Data Source object, which provides
 an interface for reading vector geometry data from many different file
 formats (including ESRI shapefiles).

 When instantiating a DataSource object, use the filename of a
 GDAL-supported data source.  For example, a SHP file or a
 TIGER/Line file from the government.

 The ds_driver keyword is used internally when a ctypes pointer
 is passed in directly.

 Example:
  ds = DataSource('/home/foo/bar.shp')
  for layer in ds:
      for feature in layer:
          # Getting the geometry for the feature.
          g = feature.geom

          # Getting the 'description' field for the feature.
          desc = feature['description']

          # We can also increment through all of the fields
          #  attached to this feature.
          for field in feature:
              # Get the name of the field (e.g. 'description')
              nm = field.name

              # Get the type (integer) of the field, e.g. 0 => OFTInteger
              t = field.type

              # Returns the value the field; OFTIntegers return ints,
              #  OFTReal returns floats, all else returns string.
              val = field.value
