Greedy snake C + + ncurses

Recently learned ncurses, with the snake training

Idea: Do not construct the linked list, the snake head to the direction of the forward point, the tail of the snake disappears, the formation of movement.

Need to record the direction of the snake head, the direction of the snake tail, and the list to mimic the queue, add inflection point information (space than the list of each node open space saving a lot)

The idea felt clearer, and it was written in a few hours.
