[Talk-ca] Start of Wiki page on StatsCan NRN data...

[Tyler Gunn]

I've started putting together a Wiki page on the StatsCan NRN data here:
http://wiki.openstreetmap.org/wiki/Statistics_Canada_%28StatsCAN%29

I'll be collecting all of my future thoughts and efforts with using this
data there, as well as providing a tutorial of how to use the data to
create address interpolation ways for an area from the NRN data.  For now I
just describe the format of the NRN files, and where to get them.
