geosshim.py Attempted Shapely support for Basemap

geosshim.py

# Note: This code does NOT work!!!

# Attempt at a shim for Shapely to work with basemap.
# This is to try to use Shapely for the code that need libgeos.

# The code is minimal on purpose.

# add this file into the lib/mpl_toolkits/basemap folder
# in __init__.py change this line:
#   import _geoslib
# to:
#   import geosshim as _geoslib
