title: How to use Ext.create properly
body: <p>Can't find any relevant information in the sencha documention about this question :</p>
  
  <p>Is it possible to call <code>Ext.create(...)</code> with a parameter which does not depend on the application's name?
  So that if I change the app's name I don't have to rewrite that line of code?</p>
  
  <p>Normally I would use <code>Ext.create(AppName.model.MYMODEL)</code> but that's too tied to the app's name for me.</p>
  
  <p>Still need help :)</p>
