/**
 * Static methods for handling of Tink configurations.
 *
 * Configurations, i.e., collections of key types and their corresponding key managers supported by
 * a specific run-time environment enable control of Tink setup via JSON-formatted config files that
 * determine which key types are supported, and provide a mechanism for deprecation of
 * obsolete/outdated cryptographic schemes (see tink/proto/config.proto for more info).
 *
 * Example usage:
 *
 * NSError *error = nil;
 * TINKAllConfig *config = [[TINKAllConfig alloc] initWithError:&error];
 * if (!config || error) {
 *   // handle error.
 * }
 *
 * if (![TINKConfig registerConfig:config error:&error]) {
 *   // handle error.
 * }
