架构练习：c语言实现贪吃蛇（二）：使用libncurses.a库实现地图和蘑菇不换页刷新

现在已经实现地图和蘑菇的，或者说游戏界面的不换页刷新，

这里需要使用libncurses.a库来实现，代码如下。

下一步：实现蛇的移动。

resource ncurses_newwin ( int rows, int cols, int y, int x);

ncurses_newwin() creates a new window to draw elements in. Windows can be positioned using x, y, rows and cols. When creating additional windows, remember to use ncurses_getmaxyx() to check for available space, as terminal size is individual and may vary. The return value is a resource ID used to differ between multiple windows.
