In DLTK, there are a cache to store AST of a source file (to avoid to re-parse file each time we need to acces to the ast)

The ast is remove from cache when :
- file is modified
- file is remove from workspace (or builpath?)

This cache management don't allow to implement a behavior which could be cool for most of editor :  when editor is  not able to parse a file (because there are a syntax error for example), return the last valid AST  for this file.

currently, we can use the cache system of DLTK because when a file is modified, it's remove from cache. so we must create our own cache system to implement this.

A way to resolve this problem, is to :
- remove file from cache when it is removed from workspace(or buildpath).
- flag the file as dirty in the cache when the file is just modified.
