The "HTML IMPORT" module

Main feature
============
- Allows user to specify heading levels at which the HTML document is divided
 and imported. For example, if H3 is selected under "Heading level depth",
 each H1, H2 and H3 will become a separate page in the imported book.
- Imports images. The module scans and fixes the paths of the images referenced
 by imported pages.
- Respects the heading level hierarchy of the source document by reconstructing
 the same book hierarchy
- Scans and re-creates reference links. Reference links in the source HTML
may be divided into different book pages
after import. The module scans and re-links the reference links to maintain
 the integrity of the document.
- Scans and moves footnotes/endnotes. If footnotes/endnotes are well-formatted,
the module scans and moves the
footnotes/endnotes to the sections where they are referenced for easy reading.
- Meets WCAG accessibility requirements. The module preserves accessibility
properties of the source HTML
such as ALT text.
- Cleans up undesirable Word characters such as smart quotes in titles
for clean URL creation
