ISSUE-41 (NULL column handling): Define how rr:column, rr:template, etc. handle NULL column values [R2RML]

Raised by: David McNeil
On product: R2RML

As far as I can see the R2RML spec doesn't address how NULL column values are handled by the rr:column and rr:template properties (are there others affected by this?).

I think possible answers are:

1) throw an error
2) do not produce triples for these rows
3) something else?

Add wording to the spec to address this.
