*Usage*

To use in a Rails app, make sure you have the hmac-sha1 gem and add this module to your /lib folder. 
Then call EnvolveChat::ChatRenderer.get_html 
from a view or helper with the appropriate keywords specified. The function will
return javascript that you can use in your page's HTML.

This ruby code:

#in Gemfile      
    gem "ruby-hmac"


#in view or helper
  EnvolveChat::ChatRenderer.get_html("123-abcdefghijklmnopqrs", 
    :first_name => user.first_name,
    :last_name => user.last_name,
    :is_admin => user.admin, 
    :pic => user.avatar(:itty_bitty), 
    :people_list_header_text => "Chat with site visitors",
    :people_here_text => "People online",
    :groups => [{:id => "forum_sec", :name => "Forum Chat"}]
  )

will produce javascript similar to:

    <script type="text/javascript">
        envoSn=123;
        env_commandString="{ command string }";
        envoOptions={peopleHereText : 'People online',peopleListHeaderText : 'Chat with site visitors',groups : [{id : 'forum_sec', name : 'Forum Chat'}]};
    </script>
    <script type="text/javascript" src="http://d.envolve.com/env.nocache.js"></script>
