# custom_batch_types hash provides hooks for handling additional batch types
# beyond the default types.  Entries can be added in a custom file.
# Each entry is a hash, keyed by name, with the following keys:
#  * map_to int (maps to another type, not needed for new types in batch_class 
#                table)
#  * select_method (maps to the selection stored proc)
#
#  for example:
#  $custom_batch_types->{ap_sample} = 
#      {map_to       => 1, 
#      select_method => 'custom_sample_ap_select'};
