#2789: Citation suggestion for Kranc

Comment (by Roland Haas):

My recollection is that Ian says that the Kranc paper is "old and
outdated". Though kranccode.org does say (http://kranccode.org/))

"We request that you cite our 2006 Kranc paper if you use Kranc, or
Kranc-generated code, in a scientific publication."

We currently list nothing for Kranc actually. Only for McLachlan.
