/**
 * Validates the contents of a pass
 *
 * This attempts to find errors with a pass that would prevent it from working
 * properly with Apple Wallet. Passes with errors often just fail to load and
 * do not provide any feedback as to the error. Additionally, some issues (such
 * as a pass not having an icon) are not well documented and potentially
 * difficult to identify. This class aims to help identify and prevent these
 * issues.
