Detailed Description

Wrapper class for evaluating transport properties using Cantera.

This class is expected to be constructed after threads have been forked and will only live during the lifetime of the thread. Note that this documentation will always be built regardless if Cantera is included in the GRINS build or not. Check configure output to confirm that Cantera was included in the build if you wish to use it.

Todo:

Need to make sure this will work in a threaded environment. Not sure if we will get thread lock here or not.
