The Create Transaction Event function allows the Device to report the product
the user purchased to the Tiliter Recognition API.
This is used to close the loop on the transaction and record when the Device
was used to follow through and purchase a product.
This also eliminates irrelevant data from reports that may result from
incomplete transactions.
Every recognition requires a transaction report; if no transaction occurs,
that can also be reported.
