-You can mark a region of a template as "constant" and not subject to
-re-rendering using the
-`{{dstache}}#constant}}...{{dstache}}/constant}}` block helper.
-Content inside the `#constant` block helper is preserved exactly as-is
-even if the enclosing template is re-rendered.  Changes to other parts
-of the template are patched in around it in the same manner as
-`preserve`.  Unlike individual node preservation, a constant region
-retains not only the identities of its nodes but also their attributes
-and contents.  The contents of the block will only be evaluated once
-per occurrence of the enclosing template.

-Constant regions allow non-Meteor content to be embedded in a Meteor
-template.  Many third-party widgets create and manage their own DOM
-nodes programmatically. Typically, you put an empty element in your
-template, which the widget or library will then populate with
-children. Normally, when Meteor re-renders the enclosing template it
-would remove the new children, since the template says it should be
-empty. If the container is wrapped in a `#constant` block, however, it
-is left alone; whatever content is currently in the DOM remains.
