/***
 * Screen - The actual point of this godforsaken project
 * 
 * This file's goal is to "render" a slot machine that the soon-to-be unlucky victim must play to get their
 * files back. To do this, I am using curses and probably the menu library to create the TUI. Once I figure
 * out how to actually do this, everything should work hopefully maybe
 * 
Example window layout

======================================================== (Window 1)         (One line long, top of screen)
VX-GAMBLEGROUND: <Random phrase from list of phrases>
======================================================== (End Window 1)     (Takes up space between top & bottom windows)
======================================================== (Window 2)

SLOTS HERE

======================================================== (End Window 2)
======================================================== (Window 3)         (One line long, bottom of screen)
> Spin              > Buy Spins             > Quit
======================================================== (End Window 3)
