Re: [Pydev-code] PyVocabulary & new developers

[Aleks T. <a...@to...>]

Hi,
moving right along on the PyDictionary implementation. I've just 
checked in the latest bunch of changes to pydev. There are few 
notable changes:

1) PyVocabulary was called PyDictionary. Goodbye grammar school, 
hello college.

The definitions dictionary (PyDictionary) is now associated with 
every PyEdit. Whenever parser completes, the definitions get updated.

Every PyDictionary holds classes/methods/locals defined inside 
the containing PyItem. The implementation still lacks a few things:
- locals are duplicated
- no methods for traversal/query

2) I've also made Parser reparse immediately after every newline. 
This gives it a much better feel.

3) Also added for all the completion enthusiasts out there are 
PyContentAssistant & PyContentAssistantProvider. These are the 
shell classes that need to be implemented for code completion.
