Suggestion - make exposing Delphi objects to python painless by utilizing the new RTTI feature in D2010 (and above) #18

Hi,

I've a suggestion - make exposing Delphi objects to python painless by 
utilizing the new RTTI (runtime type information) feature in D2010 (and above).

Currently exposing a class to the hosted Python code needs to you to write too 
much code (check demo06), I guess if we take advantage of the new RTTI feature 
in the newer versions of Delphi, the process can be improved a lot.

For example, check out the Delphi chromium embedded project, all you have to do 
to expose the interface of any Delphi class to the JavaScript environment, is 
to register the class:

// this is your class exposed to JS 
  Test = class 
    class procedure doit(const v: string); 
  end; 

initialization 
// Register your class 
  TCefRTTIExtension.Register('app', Test);

// and in JavaScript code to call that class above:
app.doit(''foo'')', '', 0); 

Cool! Isn't it?
