Tag sentences in public comment with which bill, or minutes item, or more general topic they are discussing

## Idea / Feature

Tag sentences in public comment with the general topic they are discussing but if they are additionally classified as related to a specific minutes item or bill tag it as such.

## Use Case / User Story

As a user: I want to see which public comments discussed a bill so I can quickly scan the public comments to see who commented about something and how they felt.

As a researcher: I want to quickly build a dataset of public comments about a certain topic.

## Other Notes

The issue names no files, tests, or entry points. Start by locating how public comments are stored and displayed, then determine how bill, minutes-item, and general-topic tags would be represented and checked; done means sentences can be associated with the relevant classifications for scanning and dataset creation.
