# Knows how to build the html for a section. A section is part of the visible html, that has
# content wrapped in some particular markup. Construct with the relevant options, and then
# call wrapped_html to get the resultant html.
#
# The content rendered will usually be the value of fallback_html, unless an override_html
# is specified. However, on rendering, you can elect not display sections that have no
# override_html by passing in false for can_use_fallback.
#
# Sections may be hidden, in which case they wont display at all.
