# This patch adds a convenience method to models that are including acts_as_list.
# After including it is possible to e.g. call
#
# including_instance.move_to = "highest"
#
# and the instance will be sorted to to the top of the list.
#
# This enables having the view send string that will be used for sorting.

# Needs to be applied before any of the models using acts_as_list get loaded.
