What do you exactly mean with 'code duplication'? I know there's some 
stuff that have been moved to the Manager class, and I want to get rid 
of it (maybe having the compiler init directly in Manager). However, 
most of the things are not as in normal Manager, that's wh they remain 
in Engine. If you have any other suggestions, feel free to post it here, 
I'll try to do my best to improve the Completion Engine.
However, what do you exactly need? Lexer or parser is not available 
through Completion Engine, but just type tree and method completion.

Engine has a Output rpoperty where you can directly receive the text the 
compiler sends. However, it still needs parsing :-(
