/**
 * @file
 *
 * This is a template for creating a Drupal module to extend fedora_rest
 * for your own custom content-type.  To create a module, copy this to a
 * new module folder, renamed as <custom>.module (where <custom> is the
 * name of your new module).  Also create a <custom>.info file and, if
 * you need to store any information about fedora objects beyond what
 * fedora_rest stores, a <custom>.install file.
 *
 * In this module file, set the name of your object node type and change
 * all the function names from 'template_' to the name of your module.
 * Replace or add to the calls to fedora_rest methods in each function to
 * override or extend the original behaviour.
 *
 * Be sure to add your node types info in all the fields of the array
 * created in hook_node_info()
