XLSX Writer file not closed properly

[SauloARS]

Hi,

Reporting a bug: after using $writer->close(); the file is not being released.
My Code:

$writer = WriterFactory::create(Type::XLSX);
$writer->openToFile($filename);
(...)
$writer->close();
(...)
unlink($filename);

Unlink returns an error (Permission Denied). Using windows cmd del also doesn't work.
The file can be deleted after the php process finishes.

My fix was to add one line to the close() function, in Box\Spout\Writer\AbstractWriter.php

public function close()
{
    $this->closeWriter();
    $this->isWriterOpened = false;
    fclose($this->filePointer); // Added this line
}

Good catch!
