Remove risk interpretation from the default calculator report
This is also noted in #156, but this issue is specifically related to the removal, by default, of the calculator report interpretation of risk.
We want cern.ch/cara to continue to do this interpretation, but when you run python -m cara.apps.calculator
the default page should not have this information. Initially we will run with python -m cara.apps.calculator --extra-templates ./cara_at_cern/templates
which will add back the risk interpretation.
