Description:
It draws the horizontal lines '-' first.
Draws the vertical lines using the same routine by checking if there was already a character,
in case of nothing (space), it draws using '!' character, otherwise it draws a '+'.
So, when the lines intersect it will draw a '+'.
Finally it will just copy the three '\O/' characters at the right location in screen memory.
