Add periodic encounter summary feature

[ckar364]

Description

It would be useful for users to get a periodic summary of their encounters and interactions with people on the homepage. This summary could be delivered on a weekly/monthly/yearly basis to the user. The summary should contain how many new people they have met, which people have the most new encounters added (most improved), who they have the most encounters and least encounters with. This should be delivered in a fun and engaging way that encourages users to keep connecting with new and existing people.

By having a periodic encounter summary provided to users via the homepage, they can receive a reminder on who they should contact soon, and keep track of their progress and how close they are to achieving their networking/socialisation goals.

Acceptance Criteria

• Summary is sent to users on a periodic basis
• Summary provides information on how many new people they have met

Implementation details

Consider UI design of summary for an engaging user experience. Database may be required to store statistical data.

Testing notes
