TF Mobile demo on iOS

In order to build the demo on iOS, you need Xcode 7.3 or later. Follow these steps to build the iOS demo apps:

1. Check out the TensorFlow code in a tensorflow folder in your home directory.
2. Open a terminal window and execute the following commands from your home folder to download the Inception V1 model, extract the label and graph files, and move these files into the data folders inside the sample app code:

$ mkdir -p ~/Downloads
$ curl -o ~/Downloads/inception5h.zip \
  https://storage.googleapis.com/download.tensorflow.org/models/inception5h.zip \
  && unzip ~/Downloads/inception5h.zip -d ~/Downloads/inception5h
$ cp ~/Downloads/inception5h/* \
  ~/tensorflow/tensorflow/examples/ios/benchmark/data/
$ cp ~/Downloads/inception5h/* \
  ~/tensorflow/tensorflow/examples/ios/camera/data/
$ cp ~/Downloads/inception5h/* \
