Review underlying library versions and update documentation

[lizadams]

Is your feature request related to a problem? Please describe.
I was reviewing the JTS documentation and realized that the link we provide to that library in the VERDI documentation is out of date.

https://github.com/CEMPD/VERDI/blob/master/doc/User_Manual/VERDI_ch20.md

The current location for JTS is on github.
https://github.com/locationtech/jts

I can go ahead and make the change to the documentation, but I don't know what version of JTS we are using.
JTS moved to Location Tech on Nov 3, 2016.

There are instructions on how to migrate to the new library here:
https://github.com/locationtech/jts/blob/master/MIGRATION.md

We may want to examine all of the underlying libraries and determine what version we are using and also what the cost would be to migrate to a newer/updated version of each library.

Describe the solution you'd like

1. Review underlying libraries used by VERDI.
2. Verify that the links in the documentation are correct.
3. Identify the version of the libraries currently used by VERDI.
4. Determine if libraries need to be updated.
