/**
 * strmap - an ordered map of strings to values

 * Example:
 * #include <ccan/compiler/compiler.h>
 * #include <ccan/strmap/strmap.h>
 * #include <stdio.h>
 *
 * static bool dump(const char *member, size_t value, void *unused UNNEEDED)
 * {
 * 	printf("%s at %zu. ", member, value);
 * 	// true means keep going with iteration.
 * 	return true;
 * }
 *
 * int main(int argc, char *argv[])
 * {
 * 	size_t i;
 * 	STRMAP(size_t) map;
 *
 * 	strmap_init(&map);
 * 	for (i = 1; i < (size_t)argc; i++)
 *		// This only adds the first time for this arg.
 * 		strmap_add(&map, argv[i], i);
 *
 * 	strmap_iterate(&map, dump, NULL);
 *	printf("\n");
 * 	return 0;
 * }
 * // Given "foo" outputs "foo at 1. \n"
 * // Given "foo bar" outputs "bar at 2. foo at 1. \n"
 * // Given "foo foo bar zebra" outputs "bar at 3. foo at 1. zebra at 4. \n"
