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
