Module:User:Isomorphyc/R:WoodhouseTableVersion

-- This module looks up the Greek entry title in "Module:R:Woodhouse/psia1_to_infs", a list of verbs, and adds any infinitive forms to a list including the page title itself, in both potential proper and common forms. This list of Greek forms is used to retrieve English headwords in Woodhouse's dictionary from "Module:R:Woodhouse/reverse_index".  The infinitives step is necessary because Woodhouse mostly thus identifies verbs.  The function get_page then looks up each English headword alphabetically in "Module:R:Woodhouse/page_headwords", or "Module:R:Woodhouse/page_headwords_proper", or both, per "Module:R:Woodhouse/proper_or_both", to find  page numbers in the paper edition of the dictionary.  This `abstract' page number is slightly altered with a few exceptions to obtain the page number used in the ARTFL project's URL.  These URLs are returned with bibliographical information and HTML for display. A remaining issue is that, about 5% of the time, the page number will be off by one or two.  This problem may be slightly intricate to solve completely. --

--comment for calculate_page_number_divergence: --page_number_divergence results from a few buffer pages before the first --headword, and subsequently, a few multi-page entries leaving some pages --without headwords.
