change project structure

@yonatancups 

- I have fixed the project structure further to be two different modules :
  - `example` - the example module
  - `actionSendGrdview` - the library module
- cleaned up old files that were there from other versions and removed unimportant files from version control
- changed package name from `com.citylifeapps` to `com.urbancups` - citylifeapps was the old package name we had, changing it in cups-android is not possible anymore (because the app is uploaded to Google Play) but we can at least make a fresh start for new projects)
- changed repository name to from `ActionSendGridview` to `action-send-gridview` to be consistent with the rest of our repos names

To check it out, it's best if you remove the project from your disk and clone it again. then change the branch to `refactor` and use Android Studio "Import Project" tool to open the root folder here
To add it to cups-android hit file --> import module (no need to add the example project, a choice will be given to add only the library project)
