The util.go function FunderName is linked via the template.Func map, but seems to be unused.
There is a reference in template.go to funding.Funder which cannot be found in the code. Since funding.Funder appears right next to funding.AwardNumber and there is an AwardNumber function in util.go right next to the FunderName function, funding.Funder should probably be funding.FunderName in template.go.
