the 1 to many (M) mappings between the sender and the recipients for each

will be a -> b and b -> a.
If a, b, c, d are in a group, then 4 rows containing a -> b,c,d. b -> a,c,d. etc.
Participants_info is needed to get phone numbers.
- The result of the above step is a look up table for each message. Joining this result
onto the messages table lets us know which participant a message originated from and
everyone else that received it.
