// Description :
//     Assert dialog box for LINUX. The linux assert dialog is based on a
//     small ncurses application which writes the choice to a file. This
//     was chosen since there is no default UI system on Linux. X11 wasn't
//     used due to the possibility of the system running another display
//     protocol (e.g.: WayLand, Mir)
