We should have project.properties in git it makes dependencies easier to track one of the problems is we need to keep our things in the same place. If left the way this is we will either have conflicts in this file or everyone will have to have `SlidingMenulibrary` in the same place.
I recommend either 
>(A) Changing the documentation to say put the SlidingMenuLibrary in your workspace
>OR
>(B) Creating a folder in utilities called third_party or something and update the documentation to unzip there. 
>The third_party directory (or whatever you want to call it) will need a file named .gitignore that ignores everything.
