# Class: AutocompleteSerializer
#
# Creates hash (ready for JSON serialization) with
# pairs of id => value to show in the autocomplete
# select UI.
#
# The output format of to_json is optimized for 'Select2'
# autocomplete UI.
#
# It would generate JSON of models :id and :text. Text is determined by
# #to_autocomplete method, or by #to_s.
