Very much in evolution.  Usage of those functions can be unsafe.Some Extract ProcsCan be used for extracting a whole CD cell as a Core Wire, decorated with all the instances of the CD Cell.  Useful for old Pads.  Wizards only.Registered as $PreExtractedResult comes from reading the file with the same name as obj.  Can be used for multiple VM extraction.Computing corresponding cellsGiven a schematics (source) that reflects the pin out, and the result of the extraction (in some mode), make a new cell that has same public as source, and that contains an instance of extracted. Looking for a named CellTypeUseful for Debug.Sorting Cells by number of instancesUseful type for the interpreter.Squeezing Core Structures Ê¹  –"cedar" style˜ –"Cedar" stylešœ™Icode–"Cedar" style™<Kšœ1™1—J˜ JšÏk	œœ&˜2J˜ JšÏnœœœ˜+head™Ibodyšœ_œQ™³—™šžœ˜-Jšœ#œ>œÏbœ™—šžœ˜ Jšœ™JšœXœ™f——™šžœœEœ5œœœœ˜ßKšœÄ™Ä——™š
