* A class to check the presence of a domain name, having any extension.
*
* Example of use (1):
* The following code will find all the acronyms in the text passed to the method
* and will link to the italian version of Wikipediafor further explanations
* <code>
* include_once('acronymIT.php');
*
* $text = "The PHP version 6 is under development. Read more on the WWW or get info via RSS";
* $acronymit = new AcronymIT();
* $text = $acronymit->acronym($text, 1, "it");

* echo $text;
* </code>
*
* Example of use (2):
* Listing acronyms stored in the default file, then in another one.
* <code>
* include_once('acronymIT.php');
*
* $acronymit = new AcronymIT();
* echo "File $acronymit->file:<br />"; // Will be "FIle acronyms.dat:"
* $acronymit->list_acronyms(5); // Lists the first 5 acronyms in the default file
*
* $acronymit->set_file("path/to/other_acronyms.txt"); // Changing the file
*
* echo "File $acronymit->file:"; // Will be "File path/to/other_acronyms.txt:"
* $acronymit->list_acronyms() // Lists all the acronyms in the file
