module Skyline::TranslationHelper
# Extended translate function
# ==== Parameters
# key<Symbol,String>:: the key (same as parameter to translate function)
# options<Hash>:: options(same as parameter to translate function)
# this function supports a Class in the options[:scope], ie:
# tx(:ueber, :scope => [Skyline::Page, :flashes])
# will try to translate this for Skyline::Page and all its parent classes (all descendants from AR)
# first try: translate(:ueber, :scope => [:page, :flashes])
# if that fails, it'll try: translate(:ueber, :scope => [:article, :flashes])
# (note that the Skyline module is stripped)
# if no Class is found, we'll fallback on the super function
#
# ==== Returns
# <String>:: the translation
