# Shareable module to give a #display_on?(action) method
# which returns true or false depending on an options hash.
#
# The options hash accepts:
#
# only: :index
# only: [:index, :show]
# except: :index
# except: [:index, :show]
#
# call #normalize_display_options! after @options has been set
# to ensure that the display options are setup correctly
