*	Use unreserved macro names for multiple-include protection	Ben Harris	2023-02-18
\| \| \| \| \| \| \|	Some headers used macros named like _THING_H for multiple-include protection. That style of name is reserved in ISO C, though, so I've replaced it with PUZZLES_THING_H which is my favourite of the other styles in use.
*	New puzzle! Or rather, new-ish, because this one has been lying around	Simon Tatham	2012-01-22
	in the 'unfinished' directory for a while, and has now been finished up thanks to James Harvey putting in some effort and galvanising me to put in the rest. This is 'Pearl', an implementation of Nikoli's 'Masyu'. The code in Loopy that generates a random loop along grid edges to use as the puzzle solution has been abstracted out into loopgen.[ch] so that Pearl can use it for its puzzle solutions too. I've also introduced a new utility module called 'tdq' (for 'to-do queue'). [originally from svn r9379]
