[MonoDevelop] help with refactoring

[Paul Lange]

hi there,
I'm intrested in helping with the MonoDevelop code refactoring features.
I had a look at the code and now have some questions:
* In MonoDevelop.Projects.CodeGeneration are two classes which implement 
refactoring operations (BaseRefactorer and CodeRefactorer). Which one 
should be extended and what needs to be done?
* If I for example implement class renaming there will be a new dialog. 
This is stored in MonoDevelop.Projects.Gui.Dialogs namespace. Where is 
the "glue"-code that displays the dialog and does the actions? (I'm not 
enough familiar with the MD design yet)

regards, Paul
