 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript

 * // const { ComprehendClient, StartFlywheelIterationCommand } = require("@aws-sdk/client-comprehend"); // CommonJS import

 * const config = {}; // type is ComprehendClientConfig
 * const client = new ComprehendClient(config);
 * const input = { // StartFlywheelIterationRequest
 *   FlywheelArn: "STRING_VALUE", // required
 *   ClientRequestToken: "STRING_VALUE",
 * };
 * const command = new StartFlywheelIterationCommand(input);
 * const response = await client.send(command);
 * // { // StartFlywheelIterationResponse
 * //   FlywheelArn: "STRING_VALUE",
