The EntryDescription decorator allows you to pass a format string to DescribeTable() and Entry(). This format string is used to generate entry names via:

fmt.Sprintf(formatString, parameters...)

where parameters are the parameters passed into the entry.

When passed into an Entry the EntryDescription is used to generate the name or that entry. When passed to DescribeTable, the EntryDescription is used to generate the names for any entries that have `nil` descriptions.
