Initially, the default section title was swapped within the course format
javascript functions. Though some section titles may be custom and does not
require swapping, in addition they may have links to single section view. This
introduces some callback functions for define what needs to be done in
sections libs and js files.
* Introduce function format_weeks_get_section_dates which is used
as the consistent place to calculate the current section start and
end date
* Rework callback_weeks_get_section_name to not use the above function
rather than do crazy needless looping through all sections to work
out the current week title.
* Change the just introduced is_current renderer function to share
the format_weeks_get_section_dates function to ensure both the title
and 'current week' are using the same dates to do their job
Navigation has now been re-ordered in accordance with http://docs.moodle.org/en/Development:Navigation_2.0_structure.
This has led to several changes in the way in which navigation is generated included API changes, most notably using the
navigation_nodes add method now returns the newly added node rather than the key.
At the same time the global_navigation_tree block has been renamed to navigation and settings_navigation_tree to settings.
This patch introduces two new blocks global_navigation_tree and settings_navigation_tree
both of which have been designed to make full use of the new navigation objects available through
the $PAGE object.
Bulk of this code is within lib/navigationlib.php
