class Bauxite::Action
	# Executes the specified +action+ expected to fail. If +action+ succeeds
	# the #failif action fails. If +action+ fails, #failif succeeds.
	#
	# #failif effectively negates the value of +action+. Note that this method
	# is intended to negate assertions (e.g. #assert, #assertv, #source, etc.).
	# The behavior when applied to other actions (e.g. #load, #ruby, #test,
	# etc.) is undefined.
	#
	# For example:
	#     # assuming <input type="text" id="hello" value="world" />
	#     assert hello world
	#     failif assert hello universe
	#     failif assertv true false
	#     # => these assertions would pass
	#
