# ModelReflections will be the interface between the form object and form builders like simple_form.
#
# This module is meant to collect all dependencies simple_form needs in addition to the ActiveModel ones.
# Goal is to collect all methods and define a reflection API so simple_form works with all ORMs and Reform
# doesn't have to "guess" what simple_form and other form helpers need.

      # association input.
