"""

This is a git / open / public version of cpblDefaults.py, rather than cpbl's version which includes all kinds of information about Canadian statistics, etc etc, as well as local paths.

So, you may need to define extra elements of the dict defaults, here, to make some of my other modules work.

N.B.: Once this is replaced by local settings files, merge ~/bin/cpblDefaults.py and pystata's version.
