announcing phase 3 similar and find topic operators

Phase 1 was literal operators, phase 2 was function operators, and now phase 3 we concentrate on a couple of special function operators:

find-topic[op] |x>

I'll start with similar in the next post. Heaps more to come!

previous: this concludes phase 2
