initial release

This release is based on refactoring of existing working code. Some additional features like test cases were added. While there is room for some relatively cosmetic improvements, eg: to create readme files, log summaries, example scripts in lists, shows etc - this does represent a relatively complete package for managing code in couchdb design documents - with professional programming tools like debuggers, profilers, version control, etc.
