How can I associate a codemodel item with its language?

I don't like this workaround, maybe I should fix the real issue? Or would 
associating the language with a code model result in increased disk-size for 
the repo again or something like that?

I mean grouping by file extension could potentially really be error prone, lets 
do it correctly and use the information we have... And I bet accessing the 
topducontext for every class would be too slow, right?

Though I have to admit that even in the TopDUContext I wouldn't have the 
slightest clue how to get it's language plugin to query ::name()...

The only thing I know of is the ParsingEnvironmentFilePointer, but that is 
per-url. I bet this would be a problem as soon as we have e.g. JavaScript 
support and files where we have both, JavaScript declarations and PHP 
declarations in the same file (somewhat ugly imo but you never know what users 
do...).

Can you give me some pointers on how/where to integrate something like 
ParsingEnvironmentFilePointer for CodeModel items?
