No, there is not. You can write one in PHP without too much trouble. I wrote one for debugging and testing purposes, but it is fairly specific. My design was this:

Name of CSV file was the model.
First row of CSV has the field or related object names.
Process the CSV using example code from the php website.
On the first loop, store the header row so you can figure out the field names.
Create a new object, save the fields, and save it to the database.

Here's something to get you started. It's hacked down from my code, so there may be mistakes.

Code:

// set these yourself
$csv_files = array('model1', 'model2', ...);
$path = APPPATH . 'import/';

foreach($csv_files as $model) {
    if(! class_exists($model)) {
        $this->_show_error("Error: unable to find class $model");
    }
    $handle = fopen($path . $model . '.csv', 'r');
    ini_set('auto_detect_line_endings', TRUE);
    $row = 0;
    $header;
    while (($data = fgetcsv($handle)) !== FALSE) {
        if($row == 0) {
            // save the header, ...
            $header = $data;
        } else {
            $o = new $model();
            echo "  Saving $model(";
            foreach($data as $index => $d) {
                if($index > 0) {
                    echo ", ";
                }
                echo "\"$d\"";
            }
            echo ") ... ";
            foreach($header as $index => $field) {
                if($index >= count($data)) {
                    // we've looked up everything, there must be extra header columns
                    break;
                }
                $d = $data[$index];
                // skip empty columns
                if( $d === '') {
                    continue;
                }
                if(in_array($field, $o->fields)) {
                    // save the data
                    $o->{$field} = $d;
                } else if(in_array($field, $o->has_one)) {
                    // hopefully, all of the $fields were first.  Otherwise this can be wasteful
                    $other_obj = new $field();
                    $other_obj->get_by_id($d);
                    if( ! $other_obj->exists()) {
                        $this->_show_error("Error loading relationship $field($d) on object $model: That id does not exist.");
                    }
                    if( ! $o->save($other_obj) ) {
                        print_r($o->error->string);
                        $this->_show_error("Error saving object $model($id) with one relationship to $field($d).");
                    }
                } else if(in_array($field, $o->has_many)) {
                    // hopefully, all of the $fields were first.  Otherwise this can be wasteful
                    $other_ids = explode(',',$d);
                    foreach($other_ids as $other_id) {
                        $other_obj = new $field();
                        $other_obj->get_by_id(trim($other_id));
                        if( ! $other_obj->exists()) {
                            $this->_show_error("Error loading relationship $field($other_id) on object $model: That id does not exist.");
                        }
                        if( ! $o->save($other_obj, $field) ) {
                            print_r($o->error->string);
                            $this->_show_error("Error saving object $model($id) with many relationship to $field($other_id).");
                        }
                    }
                } else {
                    $this->_show_error("Error saving object $model: No field or relationship for $field.  (Data: $d)");
                }
            }
            if( ! $o->save() ) {
                print_r($o->error->string);
                $this->_show_error("Error saving object $model with expected id $id");
            }
            echo "done.\n";
        }
        $row++;
    }
    fclose($handle);
