title: rake db:seed is not working using neo4j gem
body: <p>I have stated working on neo4j with rails using the gem 'neo4j', I want to seed some data in neo4j database. But whenever I am trying to do rake db:seed, it says </p>
  
  <pre><code>rake aborted!
  Don't know how to build task 'db:seed'
  </code></pre>
  
  <p>I have checked all the rake tasks using <strong>rake -T</strong>, and there is no <strong>rake db:seed.</strong></p>
  
  <p>Does any one have any idea?</p>
