Issue: ROBOT should fail hard if CURIE prefix is unknown
- [ ] Seems right now that robot templates does not fail hard when a prefix is unknown - instead an IRI is created in the form of a CURIE.

- [ ] I was wishing to mention that as well in general - I did have some cases what playing with SPARQL for example that I accidentally introduced curies as entity ids, and it would be kind of great if I could know about this: Maybe I should make a ROBOT report check for that?
Pull request description: Add check for malformed IRI in IOHelper.createIRI
Resolves #880

- [ ] `docs/` have been added/updated
- [x] tests have been added/updated
- [x] `mvn verify` says all tests pass
- [x] `mvn site` says all JavaDocs correct
- [x] `CHANGELOG.md` has been updated

This is a bit more sane than trying to do a regex match for a valid URL. If the output IRI is just a CURIE, this will fail (e.g., undefined prefix when running `template`). If the output IRI has a space it it, this will also fail (which we were just checking for a space before).

 This example will only include the first 10,000 results for each report query, meaning that some violation counts may be incomplete. Typically, you should not need to include a limit, but when working with large ontologies (using TDB), there may be hundreds of thousands of results.
 
+The results can also be restricted to entities following one or more URI prefixes.
+
+```
+robot report --input edit.owl \
+  --base-iri "http://purl.obolibrary.org/obo/UBERON_" \
+  --base-iri "https://github.com/ontodev/robot/examples/edit" \
+  --base-iri "http://purl.obolibrary.org/obo/UBPROP_" \
+  --output my-base-report.tsv
+```
+
+Note that if you want annotations on your ontology itself be checked, be sure to
+include a suitable URI prefix. For example, in the snippet above, we have
+included `https://github.com/ontodev/robot/examples/edit`, which ensures that
+ontology annotations on `https://github.com/ontodev/robot/examples/edit.owl` are
+included in the test results.
+
 ## Working with import closures
 
 By default the report command will operate over the specified ontology, ignoring the import chain. This means if your ontology uses a class, and the class label is asserted in an import, you will receive a missing label error.
