[Flask] Jinja environment finalize function

Jinja allows one to initialize an environment with a 
"finalize" callable, which I want to do to convert None's
to empty strings before they are output.  This is much 
cleaner than than filling my templates with innumerable
"if none ..." constructs.

But I don't see in the Flask docs how to do this.
