title: Need examples for Entityframework.HierarchyId
body: <p>I found EF.HierarchyId on NuGet. Looks like EF6.1.1 supports it now?</p>
  
  <p>Wondering if there are any documentation I can see about how to use it.
  For example: </p>
  
  <p>-does it work with edmx? may it import models with hierarchyId column?</p>
  
  <p>-some linq examples? what commands are supported?</p>
  
  <p>Thank you.</p>
