FreshBox:配方配料应用

保鲜盒配方/配料应用 Thiis是由Sylvia，Joy和John组成的班级小组工作的一部分，是一款Android Recipies和ingridients订购应用程序。该应用程序的后端使用parse.com。实现的其他库包括用于地理位置和跟踪的地图，用于前端的侧边菜单.android等其他工具。

The `echo` command with `$(VAR)` will print the value of the `VAR` variable with leading and trailing spaces, while the `echo` command with `$(strip $(VAR))` will print the value of `VAR` with leading and trailing spaces removed.
