	and use it in extracthocrlines
2021-02-09	hocr: Use extracted page name for line naming	Nick White
	This means that even in multi page hocrs with lines with the same id (like line_1_1), then the page name will be different, so extracthocrlines now won't mistakenly name different lines the same and therefore overwrite them.
2021-02-09	hocr: Use image specified in ocr_page title, so can support multipage hocrs ↵	Nick White
	cleanly
2020-04-14	Add godoc documentation	Nick White

2020-03-13	Add copyright statements to each file	Nick White

2019-10-31	Export a couple of more generally useful functions	Nick White

2019-10-30	Simplify and document hocr package slightly better	Nick White

2019-10-23	Make bucket-lines and related packages more robust	Nick White
	bucket-lines would crash for any line that didn't have a corresponding image. Lines which weren't grayscale would also cause crashes; now they are just converted to grayscale if necessary. As a bonus, lines in jpeg can also be decoded successfull.
2019-10-08	Remove parts that have been moved elsewhere, and rename to rescribe.xyz/utils	Nick White
	bookpipeline is now at rescribe.xyz/bookpipeline preproc is now at rescribe.xyz/preproc integralimg is now at rescribe.xyz/preproc/integralimg
