This makes a couple of changes to the xblock handler in the CMS. These changes add a handful of utility functions and modify the existing ones to make reuse of existing blocks easier. With these changes, it is possible to copy an entire section from one course to another, and then later refresh that section, and all of its children, without destroying the blocks next to it. The existing _duplicate_block function was modified to have a shallow keyword to avoid copying children, and the update_from_source function was added to make it easy to copy attributes over from one block to another. These functions can be used alongside copy_from_template in the modulestore to copy over blocks and their children without requiring them to be within any particular container (other than a library or course root)-- thus allowing library-like inclusion without the library content block. This is especially useful for cases like copying sections rather than unit content.
CMS
===
This directory contains code relating to the Open edX Content Management System ("CMS"). It allows learning content to be created, edited, versioned, and eventually published to the `Open edX Learning Mangement System <../lms>`_ ("LMS"). The main user-facing application that CMS powers is the `Open edX Studio <https://edx.readthedocs.io/projects/open-edx-building-and-running-a-course/en/latest/getting_started/CA_get_started_Studio.html#>`_
