SlideRule version error can be clarified

[akhuller]

When running SlideRule via CryoCloud using a sample notebook (https://slideruleearth.io/web/rtd/getting_started/Examples.html), the user gets the following error: "Client (version (4, 12, 3)) is out of date with the server (version (4, 14, 4))". Perhaps it could be clarified that this is merely a warning, and the subequent code in the notebook will still run regardless?
