Making a list of high-profile libraries that use pyshp

[karimbahgat]

As a future addition to the README, we want to add a "Used By" section that lists high-profile or interesting examples of libraries that rely on pyshp. Here's a non-complete preliminary list that I'll keep adding to:

• ESRI ArcGIS API
• Cartopy
• Matplotlib Basemap
• ObsPy
• NOAA PyFerret
• USGS PEST++
• USGS SFRmaker
• USGS FloPy
• Rhino/Grasshopper GHSHP plugin
• Rhino/Grasshopper ShrimpGIS plugin
• landlab

If you know of any interesting examples that you think should be included, please post it in a comment below.
