+
+This is for anyone that cares about how long a user is signed
+in:
+
+Currently I have a user to be signed in forever unless they
+log out (cookies.permanent....).
+
+If you want to change that, change line 7 to this:
+
+cookies[:remember_token] = { value: remember_token, 
+                            expires: 20.years.from_now.utc }
+
+which will expire the cookie in 20 years from its date of
+creation.
+
+Oddly enough, this line above is equivalent to the:
+
+cookies.permanent
+
+This is just a short cut for this line since most people 
+create permanent cookies these days.
+
+Other times are:
+
+10.weeks.from_now
+
+5.days.ago
+
+etc...
