The class "Export" produces a csv file. It receives an array
and returns a csv file only for downloads.
Use: Either as class call or invoke:

use Palvoelgyi\CsvExport\CSVExport;

$dataArray = [ 
    [ 'Header 1', 'Header 2', 'Header 3' ],
    [ 'TEST 4',   'TEST 5',   'TEST 6'   ],
    [ 'TEST 7',   'TEST 8',   'TEST 9'   ],
    [ 'TEST 10',  'TEST 11',  'TEST 12'  ],
];

$CSV = new CSVExport;
$CSV($dataArray);

or

$CSV = new CSVExport;
$CSV->setData($dataArray)
->generateCSVFile()
->getCSVFile();

It is possible to create the first line with the original name:
$csv = new CSVExport (1);

Or to define fields yourself:
$csv = new CSVExport ();
For this you have to change the variable "$header" under "CSVExport.php".
