Compares the Keras Layer Nodes against the DL Python nodes. Builds four models which attempt to predict future sales. Two models predict "Today's Sales" (which are already known to the model). The other two models predict "Tomorrow's Sales" which correlate to the sales from the same-day-last-week. Viewing the node weights show how the models identify the most useful inputs.
