//! A wizard for adding friends. Based on standard QWizard component

//! The process of adding friends follows this scheme:
//!         /-> Use text certificates \       /-> errorpage(if  went wrong)
//! intro -|                           |-> ->
//!         \-> Use *.pqi files      /        \-> fill peer details
//!  
//! So, there are five possible pages in this wizard.
