	=head1 OVERVIEW

	When a user enters a course, LON-CAPA examines the course structure
	and caches it in what is often referred to as the "big hash". You
	can see it if you are logged into LON-CAPA, in a course, by going
	to /adm/test. (You may need to tweak the /home/httpd/lonTabs/htpasswd
	file to view it.) The content of the hash will be under the heading
	"Big Hash".

	Big Hash contains, among other things, how resources are related
	to each other (next/previous), what resources are maps, which
	resources are being chosen to not show to the student (for random
	selection), and a lot of other things that can take a lot of time
	to compute due to the amount of data that needs to be collected and
	processed.

	Apache::lonnavmaps provides an object model for manipulating this
	information in a higher-level fashion then directly manipulating
	the hash. It also provides access to several auxilary functions
	that aren't necessarily stored in the Big Hash, but are a per-
	resource sort of value, like whether there is any feedback on
	a given resource.

	Apache::lonnavmaps also abstracts away branching, and someday,
	conditions, for the times where you don't really care about those
	things.

	Apache::lonnavmaps also provides fairly powerful routines for
	rendering navmaps, and last but not least, provides the navmaps
	view for when the user clicks the NAV button.

	B<Note>: Apache::lonnavmaps I<only> works for the "currently
	logged in user"; if you want things like "due dates for another
	student" lonnavmaps can not directly retrieve information like
	that. You need the EXT function. This module can still help,
	because many things, such as the course structure, are constant
	between users, and Apache::lonnavmaps can help by providing
	symbs for the EXT call.

	The rest of this file will cover the provided rendering routines,
	which can often be used without fiddling with the navmap object at
	all, then documents the Apache::lonnavmaps::navmap object, which
	is the key to accessing the Big Hash information, covers the use
	of the Iterator (which provides the logic for traversing the
	somewhat-complicated Big Hash data structure), documents the
	Apache::lonnavmaps::Resource objects that are returned by

Encapsulating the compiled nav map

navmap is an object that encapsulates a compiled course map and
provides a reasonable interface to it.

Most notably it provides a way to navigate the map sensibly and a
flexible iterator that makes it easy to write various renderers based
on nav maps.
