@swinslow and @rtgdk, I've added example script to use rdf loader via this PR. Please suggest changes if any. :)

Looks good! Two comments:

• I see that this is missing the SPDX license statement at the top of the file, but I saw also that you added that in 058a618 (Add rdfSaver Files #14) so no need to add it in this current PR.
• I think this is demonstrating some problems with the parsing. E.g., when I run it against the example RDF file you included, I see that it is printing two package names but both are named glibc. It appears that one of them should be named Saxon based on the sample file.

For the second point, see

tools-golang/examples/7-load-Rdf/examplerdf2v1.rdf

Line 763 in be473af

<spdx:name>Saxon</spdx:name>

This is something we should address but I am guessing it is a problem with the rdfloader code, not in this example file. So I will go ahead and merge this PR.
