Creates a dataset pipeline from GAME_GENERATOR_DATASET by:
1) Applying the function gameToFeaturesAndlabel
2) Taking the first N samples of the dataset
3) Batching the dataset to batches of size B

It then executes the dataset by filling an array.  Finally, it passes this
array to the UI to render in a table.
