webrat: scope.rb#select_date

	# Verifies that date elements (year, month, day) exist on the current page
	# with the specified values. You can optionally restrict the search to a specific
	# date's elements by assigning <tt>options[:from]</tt> the value of the date's
	# label. Selects all the date elements with date provided. The date provided may
	# be a string or a Date/Time object.
	#
	# Rail's convention is used for detecting the date elements. All elements
	# are assumed to have a shared prefix. You may also specify the prefix
	# by assigning <tt>options[:id_prefix]</tt>.
