{{#invoke:LDSverse|function name}}

See Template:LDS (edit talk links history) for usage documentation.

-- This module implements the lion's share of the newly-revised-as-of-August-2020 Template:LDS.
local p = {}

-- TODO:
--	Check the verse parameter to make sure it's a number (sometimes users 
--		mistakenly include the en dash and ending verse number in this 
--		parameter, e.g., {{LDS|Alma|alma|7|11–12}}). If it isn't a number, 
--		default to citing to the chapter as a whole?
--	Take out the remaining error statements and handle errors more gracefully.
--		(As of September 2020, many have already been removed, so that's good.)
--		Functions with error statements left in them:
--			getFullBookName
--			handleOD
--			getStandardWork (only throws an error if pre-conditions not met)
--			getLectureOrdinal (only called with pcall)

	First: define bomBooks, dcBooks, pogpBooks, lofBooks, and bibleBooks
	These tables (one for each Standard Work) are the heart of the module.
	They have the following structure:
		The key is the "correct" name of the book, defined as how it is titled
			on Wikisource
		The value for each book is an array of other names it might be known by.
			Some of these are standard abbreviations, some are common typos 
			(e.g., "Revelations"), and some are included to ensure backwards 
			compatibility with the original {{LDS}} template (e.g., 1_jn).
			NB: The values do not contain capitalization variants, as those will
			be tested for in the logic (since these tables are already huge).
	The tables are then themselves stored in an array titled standardWorks
