This package is used to manage user sessions in generic web applications, where managing access control is a desirable feature.

0. You've already established the various kinds of sessions you're interested in tracking, by making calls to yourSession := session.NewSession.
1. User has successfully logged in, by jumping over whatever hurdles you've constructed.
2. You create a corresponding session entry, with yourSession.Begin(uname), which gives you back the token's time to live duration, and the token itself.
3. The user tries to do some activity with controlled access.
4. You call yourSession.Validate(uname, providedToken) to validate a token.
5. Your user's browser, realizing that their token's time is coming up, requests a renewal.
6. You call yourSession.Renew(uname, providedToken), which will return a brand new token and time-to-live.

1. Allow for custom token parameters

• Tokens that expire at different times, are different lengths, etc.

2. Allow for custom tokens

• Tokens that grant access to X activity or Y activity.
  • We can encode this information in a couple of ways. For example by making separate DB indices, or by hashing the activity name into the token.
• Allow users to possess more than 1 token.

1. SecureSession, which only stores hashes of usernames/ids.

What if we want to make two different kinds of token for the same username?

We would need separate redis DBs, one for each user. Or, we could just use username_tokenName as the index. Way better idea.
