Hash#value_at_path

	class Hash
	# Returns the value at the specified path.
	# For example, [:foo, :bar, :baz] as a path would return the
	# value at self[:foo][:bar][:baz]. If self doesn't contain one of
	# the keys specified in path, nil is returned.
	#
	# This method is useful as it simplifies statements such as:
	# value = h[:a][:b][:c][:d] if h[:a] && h[:a][:b] && h[:a][:b][:c]
	# to
	# value = h.value_at_path(:a, :b, :c, :d)
