foreach( $files as $file ) {
    $meta = $file->getMeta();

    $meta->version;  # cache grind file version
    $meta->creator;  # creator, xdebug 2.1.1... or something
    $meta->cmd;
    $meta->part;
    $meta->positions;


    $result = $file->parse();   // get parser result.


    $parser = new GrindKit\GrindParser( $file );
    $result = $parser->parse();

    $result->functions;  // function list
    $result->summary;    // summary table
