 /**
  * Defines function signatures for resources available to services.
  *
  * Functionally this is very similar to the way hook_menu() works, and in many
  * ways Services can be seen as an abstraction layer on top of hook_menu().
  *
  * @return
  *   An associative array which defines available resources.
  *
  *   The associative array which defines services has five possible top
  *   level keys. The operations array has five possible keys representing
  *   the CRUD operations.
  *
  *     - #api_version
  *     - operations
  *       - create
  *       - retrieve
  *       - update
  *       - delete
  *       - index
  *     - actions
  *     - targeted_actions
  *     - relationships
  *
  *   The #api_version is the services resource API that the resource is written
  *   for. This makes it possible for services to upgrade resource declarations
  *   if the format changes. See services_resource_api_version_info(). If no
  *   version is given then 3001 is assumed. Which is the format used before the
  *   versioning was introduced.
  *
  *   The CRUD functions in 'operations' are pretty self-explanatory. Index is
  *   an extra CRUD-type function that allows you to create pageable lists.
  *
  *   Actions are performed directly on the resource type, not a individual
  *   resource. The following example is hypothetical (but plausible). Say
  *   that you want to expose a API for the apachesolr module. One of the
  *   things that could be exposed is the functionality to reindex the whole
  *   site at apachesolr/reindex.
  *
  *   Targeted actions acts on a individual resource. A good, but again -
  *   hypothetical, example would be the publishing and unpublishing of nodes
  *   at node/123/publish.
  *
  *   Relationship requests are convenience methods (sugar) to get something
  *   thats related to a individual resource. A real example would be the
  *   ability to get the files for a node at node/123/files.
  *
  *   The first five (the CRUD functions + index) define the indvidual service
  *   callbacks for each function. However 'actions', 'targeted_actions',
  *   and 'relationships' can contain multiple callbacks.
  *
  *   For those familiar with Services 2.x, these callbacks are created
  *   similarly, but the keys have changed around a bit. The following keys
  *   are used to describe a callback.
  *
  *   - help: Text describing what this callback does.
  *   - callback: The name of a function to call when this resource is
  *     requested.
  *   - file: an array describing the file which contains the callback
  *     function
  *   - access callback: The name of a function to call to check whether
  *     the requesting user has permission to access this resource. If not
  *     specified, this defaults to 'user_access'.
  *   - access callback file: an array describing the file which contains the
  *     access callback function.  This attribute only needs to be supplied if
  *     the method callback and the access callback are defined in different
  *     files, for example when a method callback is overridden using
  *     hook_services_resources_alter but the access callback is not
  *   - access arguments: The arguments to pass to the access callback.
  *   - access arguments append: A boolean indicating whether the resource's
  *     arguments should be appended to the access arguments. This can be useful
  *     in situations where an access callback is specific to the particular
  *     item ('edit all nodes' vs 'edit my nodes'). Defaults to FALSE.
  *   - args: an array describing the arguments which should be passed to this
  *     resource when it is called. Each element in the array is an associative
  *     array containing the following keys:
  *
  *     - name: The name of this argument.
  *     - type: The data type of this argument (int, string, array)
  *     - description: Text describing this argument's usage.
  *     - optional: A boolean indicating whether or not this argument is optional.
  *     - source: Where this argument should be retrieved from. This can be
  *       'data' (indicating the POST data), 'param' (indicating the query
  *       string) or 'path' (indicating the url path). In the case of path,
  *       an additional parameter must be passed indicating the index to be used.
  *     - default value: this is a value that will be passed to the method for
  *       this particular argument if no argument value is passed
  *
  *   A detailed example of creating a new resource can be found at
  *   http://drupal.org/node/783460 and more information about how
  *   REST resources are managed can be found at http://drupal.org/node/783254.
