Consider adding an example on how to run this for all repos in an organization

For instance

```shell
curl "https://api.github.com/orgs/ORGNAME/repos?page=1&per_page=100" > ORG-page-1
cat ORG-page-1 | jq -r '.[].svn_url' > repo-list-page-1.txt
# Repeat for more pages
cat repo-list-page-*.txt > repo-list.txt
fairtally --output-file ORG.html --input-file repo-list.txt
```
