title: Eclipse DLTK: JDT-like behaviour of parsing and managing files in a project
body: <p>i'm developing a plug-in for eclipse using the DLTK framework. This question was asked on the official mailing list but is unanswered yet, so i want to make it more public.</p>
  
  <p>in my DLTK plug-in, as for now, files are only parsed when the editor is opened on a file. Is there a way to achieve a parsing strategy similar to the eclipse jdt in which all files of a project are parsed together? or is that not supported by DLTK and do i have to implement an own strategy and caching model?</p>
  
  <p>thanks in advance.</p>
