Get script into version control

[ramanshah]

To use townmunculus from the command line, I have a one-line script called tm in my path:

(base) ~/Dropbox/b/g/projects> cat /usr/local/bin/tm
#! /bin/bash

Ag "$*" ~/b/r/townmunculus/cities_and_counties.csv

In practice, this is awesome. I've even used it, e.g., during phone and Zoom calls:

(base) ~/Dropbox/b/g/projects> tm Ann Ar
13534:Ann Arbor charter township,Michigan,fb5a68b3,4498
13535:Ann Arbor city,Michigan,98ed983d,119280

Get such a one-liner into this repo (a more portable one, based on grep), and provide workflow/documentation to get it into the user's $PATH.
