root to the current one, specified by category.
agent is the agent identifier returned by a previous

may return the following array:
$array[0] will contain ”
$array[1] will contain ‘Root’
$array[2] will contain ’02′
$array[3] will contain ‘Sport’
$array[4] will contain ’0203′
$array[5] will contain ‘Auto’
$array[4] will contain ’02031D’
$array[5] will contain ‘Ferrari’

Example 1.
Specifying path to the current category in the following format:
‘> Root > Sport > Auto > Ferrari’

  $cat_path_arr = udm_cat_path($udm_agent, $cat);
  $cat_path = '';
  for ($i=0; $i<count($cat_path_arr); $i+=2) {
    $path = $cat_path_arr[$i];
    $name = $cat_path_arr[$i+1];
    $cat_path .= " > <a href=\"$_SERVER[PHP_SELF]?cat=$path\">$name</a> ";
