title: Using tank_auth with multi type user and HMVC
body: <p>Using Tank Auth for first time along with HMVC. In my application there are 2 type of user one is say student and another is institute.<br>
   I created two modules for each user type and separated the tank auth library , both user's registration, login and tables are different from each other.  </p>
  
  <p>Now if I try to add any other page which is common to both users like home page, Which library should be used.<br>
    I know there must be better solution to handle multiple user problem.
  Please let me know where I'm doing wrong. And what should I do to tackle this problem.</p>
