Returns metadata describing supported tokens.

The metadata array contains token type, name, and description data as well as an optional pointer indicating that the token chains to another set of tokens.

For example:

$data['types']['node'] = array(
  'name' => t('Nodes'),
  'description' => t('Tokens related to node objects.'),
);
$data['tokens']['node']['title'] = array(
  'name' => t('Title'),
  'description' => t('The title of the current node.'),
);
$data['tokens']['node']['author'] = array(
  'name' => t('Author'),
  'description' => t('The author of the current node.'),
  'type' => 'user',
);
