GRC Code Organization

These notes are an attempt to figure out how big of a project porting from pygtk to pyqt will be, by identifying which files have pygtk code and how much of it.

/gnuradio
  /grc
    /blocks - no pygtk, these are just yml definitions for built in blocks (e.g. variable, pad, options, note)
    /converter - no pygtk, this is code to convert from old xml to new yml format
    /core - 
    /gui
    /scripts - contains gnuradio-companion and grcc scripts, which have a few lines of pygtk
    /tests - no pygtk, just a bunch of test scripts
