新式菜单
测试系统版本：CentOS 6.4 x86_64
作用：提供彩色画面，实现方向键控制
实现：根据窗口大小确定各元素位置，彩色输出，各元素组件可选择是否输出。
各个菜单项切换的实现方式：原菜单项常规输出，新位置的菜单项使用特殊效果输出，箭标跟随移动。（添加应用函数或者脚本的方式，参考源代码注释中关于变量的部分）
演示：
查看可使用的选项，主要是控制颜色或各组件是否需要输出，可混合使用
没有任何参数（sh memu.sh）
可使用上下左右方向键进行控制，也可以使用菜单中出现的字母序号跳转位置
sh menu.sh --nocolor 使用加颜色的效果
将所有效果和组件不输出
sh menu.sh --notitle --noinfor --nodate --noframe --nocolor
