An initializer to show what parts of your page come from what rails partials

	# Start the app with EXPLAIN_PARTIALS=true to show locations of view partials
	if Rails.env.development? and ENV['EXPLAIN_PARTIALS']
	module ActionView
	class PartialRenderer
	def render_with_explanation(*args)
	rendered = render_without_explanation(*args).to_s
	# Note: We haven't figured out how to get a path when @template is nil.
	start_explanation = "\n<!-- START PARTIAL #{@template.inspect} -->\n"
	end_explanation = "\n<!-- END PARTIAL #{@template.inspect} -->\n"
	start_explanation.html_safe + rendered + end_explanation.html_safe
