/**
 * idtree - id allocation tree
 *
 * There are often cases where you want to provide an integer handle for
 * some data, and easily map it back to another structure.
 *
 * idtree is an efficient implementation of an int->void * mapping, with
 * assignment of the lowest available id number.  It is from the Linux kernel
 * via the Samba project.
 *
 * Example:
 *	#include <ccan/idtree/idtree.h>
 *	#include <ccan/talloc/talloc.h>
 *	#include <stdlib.h>
 *	#include <stdio.h>
 *
 *	// Silly example which puts args in the idtree and retreives them
 *	int main(int argc, char *argv[])
 *	{
 *		struct idtree *idtree = idtree_new(NULL);
 *		unsigned int i;
 *	
 *		// This will return consecutive id numbers.
 *		for (i = 0; i < argc; i++) {
 *			printf("idtree_add('%s') -> id %i\n",
 *			       argv[i], idtree_add(idtree, argv[i], -1));
 *		}
 *		for (i = 0; i < argc; i++) {
 *			printf("id %i -> '%s'\n",
 *			       i, (char *)idtree_lookup(idtree, i));
 *		}
 *		return 0;
 *	}
