-## CHANGELOG:
-## ====================
-## Version 1.2
-## 1. Fixed bugs involving missing imports now that these classes are in
-## their own module.
-## 2. Added doc strings for ePyDoc.
-## 3. Renamed helper functions, vars etc. not intended to be visible in public
-## interface to code.
-##
-## Version 1.1
-## Made ipaddrctrls allow right-insert in subfields, now that insert/cut/paste works better
