Adds the definition of tags to the given class. This method adds two
groups of triples.
The first group of triples uses the BRICK.hasAssociatedTag property
to associate the tags with this class. While this is duplicate information,
it is much easier to query for.
The second group of triples uses SHACL-AF rules to generate the appropriate
Brick class from a set of tags. Strict equality of the tag set is required:
if two classes which are *not* related by a subclass relationship exist, but
one class's tags are a strict subset of the other, then under this regime
the subsumed class will *not* be inferred for instances of the class with more
tags.
