Broadening this ticket to include replacement of menu.ctp with top-of-page menus.
New default layout should have a "Powered By COmanage" logo at the bottom.
As per today's conversation, the CO selector will go away and the drop down menus will be sorted by CO. eg:
Organizations >> LIGO >> My Population >> MyCOU1
"Organizations" probably needs to be renamed.
Also, need to confirm if the menus are properly I18Nified.
