module Phlexible
#
# Helper to assist in defining page titles within Phlex views. Also includes support for nested
# views, where each desendent view class will have its title prepended to the page title. Simply
# include the module and assign the title to the `page_title` class variable:
#
# class MyView
# include Phlexible::PageTitle
# self.page_title = 'My Title'
# end
#
# Then call the `page_title` method in the <head> of your page.
#
