[IOT Lab] Confusing naming of "Stream Processing" and "CosmosDB" functions

[deborahc]

In the lab, the role of the function named "StreamProcessing" is to trigger when items are sent to IOT hub and write it to Cosmos DB "telemetry" collection. The name "StreamProcessing" is confusing here, because in the diagram, it is named "Event Processing," so it is hard to find on the diagram.

It is also easy to confuse, because there is another function called "CosmosDB," which is triggered off "telemetry" collection to send data to Event Hub, which is an input for Stream Analytics. The naming of "StreamProcessing" function makes it seem like it's a function that is directly connected to Stream Analytics, which it is not.

In addition, the function called "CosmosDB" is called "Trip Processing" in the diagram.

Suggestions: Rename the functions to be consistent with the diagram, or add a note in the lab explaining the mapping of how the name appears in Visual Studio to the diagram.
