Add a lexicon for the Hebrew/Greek text

Greek Text (interword): I really like the ability to see the Greek and the word-by-word translation. There are a few obscure items, such as (vvv); it would be helpful to have a glossary or other descriptive page that explains how this interword rendering works and what the tags mean. I presume (vvv) means the word is part of a verb phrase, but I haven't looked closely enough to be sure of that.

I'm not sure what the vvv is either. My guess is that the data isn't complete in the source materials. But, it would be better to include a full lexicon with better notes as in the GBT app.
