Update README

Update README to better tell the user that this repository is for
code samples for Oxford Properties's iOS Game: Recycling Kiosk
Add Code Samples For Recycling Kiosk

Add in the code samples that I have done for Recycling Kiosk
because this will allow visitors to my site to view what I have done
for this site.
Update README To Update Some Text

Remove text "table names and columns" because it is in adequate
since the database for the app has been completed removed. Also,
change site to app to be more adequate.
