Track active users sessions in redis.

Add this line to your application's Gemfile:

gem 'session_tracker'

And then execute:

$ bundle

Or install it yourself as:

$ gem install session_tracker

In your ApplicationController:

before_filter :track_active_sessions

def track_active_sessions
  SessionTracker.new("user", $redis).track(session[:session_id])
end

Then to view the current state:

SessionTracker.new("user", $redis).active_users

If redis is accessible through $redis, you don't have to give it as an argument to SessionTracker.new.

Read the spec and/or code to see how it works.

3. Commit your changes (git commit -am 'Added some feature')
