Add command-line option to warn on undefined keys #72

Closed joshhansen closed 3 years ago

joshhansen commented 4 years ago

Just a little something I find convenient when diagnosing my templates. if the -w or --warn flag is provided on the command line, or warn=True to render, a simple warning will be printed to stderr on each key referenced by the template but not defined in the data.
