implemented basic functions:

- send a location from Telegram to bot
- query a list (7) of POIs from Foursquare
- send user inline keyboard button to choose a location
- post toot status update to Mastodon with a link to OSM
- store previously seen locations in local db

 # Swarm2Fediverse
 
 Foursquare Swarm like Telegram bot to checkin at places and post to Fediverse (Mastodon/Pleroma)

+TODO:
+
+- Attach up to four images to each checkin
+- Set default checkin visibility to followers-only and add option to set individual checkin visibility
+- Amazon .bot domain
+- i18n
+- Anonymized analysis
+- OAuth login to Mastodon/Pleroma
+- Delayed checkins
