##
# A {Capybara::Result} represents a collection of {Capybara::Node::Element} on the page. It is possible to interact with this
# collection similar to an Array because it implements Enumerable and offers the following Array methods through delegation:
#
# * []
# * each()
# * at()
# * size()
# * count()
# * length()
# * first()
# * last()
# * empty?()
#
# @see Capybara::Node::Element
