 This PHP class can convert an array into ascii text table.
+
+## Example Usage:

+```
+require_once ('ArrayToTextTable.php');
+
+$data = array(
+	array('company'=>'AIG', 'id'=>1, 'balance'=> '-$99,999,999,999.00'),
+	array('company'=>'Wachovia', 'id'=>2, 'balance'=> '-$10,000,000.00'),
+	array('company'=>'HP', 'id'=>3, 'balance'=> '$555,000.000.00'),
+	array('company'=>'IBM', 'id'=>4, 'balance'=> '$12,000.00')
+);
+
+$renderer = new ArrayToTextTable($data);
+$renderer->showHeaders(true);
+$renderer->render();
+```
+### Output of above example
+```
++----------+----+---------------------+
+| COMPANY  | ID |       BALANCE       |
++----------+----+---------------------+
+| AIG      | 1  | -$99,999,999,999.00 |
