/*
* This class extends code from rtfclass.php that was written by Markus Fischer by uncompression and modifications to return ascii text.
*
* Coded by me (Andreas Brodowski) to allow compressed RTF being uncompressed by code I ported from Java to PHP and adapted according the
* needs of Z-Push.
*
* Currently it is being used to detect empty RTF Streams from Nokia Phones in MfE Clients
*
* It needs to be used by other backend writers that needs to have notes in calendar, appointment or tasks
* objects to be written to their databases since devices send them usually in RTF Format... With Zarafa
* you can write them directly to DB and Zarafa is doing the conversion job. Other Groupware systems usually
* don't have this possibility...
