UpdateJSON.displayTable()
The UpdateJSON.displayTable()
method simply writes the entire table to the command line.
This method does not format the table's contents in any significant way. It is simply provided as a convenience to allow the user to see that data has in fact been modified in the store.
// Dumps the entire table to the command line.
// Output is unformatted.
