*
* History:
* Jarno Elonen created the original script and basic functions
* Sarah King converted the functions to a class and built in user management routines
* Horst Nogajski  - built in group-support and extra infos (both optional)
*                 - uses Apache-Style MD5-Cryption Passwords. Now works cross-platform (win,unix)!
*                 - built in CSS-Styles for more useability
*                 - built in Validation (min-max length, allowed Chars) for all entries
*                 - LockingMechanism is more robust. Needed, because now every user may
*                   send (lots) requests with writeaccess to the file(s), (password or info)
*                 - and some more 'hardening'
