How to setup Heroku Hostname SSL with GoDaddy SSL Certificate and Zerigo DNS
Heroku recently added an exciting new 'Hostname SSL' option.  This option offers the broad compatibility of IP-based SSL, but at 1/5 the price ($20 / month at the time of this writing).  
 
The following tutorial explains how to use Heroku's new 'Hostname SSL' option on your Heroku project.  Before we begin, let's list what we're using here:

    * Heroku Hostname SSL
    * GoDaddy Standard SSL Certificate
    * Zerigo DNS

Note: I am not using the Heroku Zerigo DNS add-on, instead I have a separate Zerigo account for my DNS needs.  I do this because Zerigo offers 30 hosts on free direct accounts, versus only 10 hosts on the free Heroku add-on.
