(SHACL → ShEx) Convert a simple SHACL shapes graph to ShEx

It is possible to convert a SHACL shapes graphs to ShEx schemas.

rudof convert -m shacl -x shex -s examples/simple_shacl.ttl -f turtle -o target/simple.shex

Limitations

The converter only works for a subset of SHACL. We should still document what are the features supported and the features that are not yet supported but this is still work in progress.
