Minimal functionality, with a simple popup
minimal change on the presentation
Yay! I can move a block around
Changed NCurses engine from default `Curses` to gem `FFI-Ncurses`. Its a "close-to-the-metal" ncurses wrapper, which makes development easy.
Made all pieces/blocks independent of their window (fixed minor things)
All the pieces are defined! Dis gun b gud
Created Board (also, can lock pieces into it)
