aws-solutions-constructs.aws-lambda-sqs-lambda

Create a mini-application that serves as a simple message processing system using AWS CDK constructs. This application will utilize the 'aws-solutions-constructs.aws-lambda-sqs-lambda' package to handle message generation, storage, and consumption. The application should follow these steps and include the specified features:

1. **Message Generation**: Implement a Lambda function that generates messages and sends them to an SQS queue. These messages could be simple text strings or JSON objects containing various data points.
2. **SQS Queue**: Utilize the provided package to create an SQS queue where messages from the first Lambda function will be stored temporarily.
3. **Message Consumption**: Develop another Lambda function that reads messages from the SQS queue and processes them. This could involve logging the messages, transforming the data, or triggering additional actions based on the content of the messages.
4. **Error Handling**: Ensure that your application includes robust error handling for both message generation and consumption. For instance, if a message cannot be processed successfully, it should be moved to a dead-letter queue for further inspection.
5. **Monitoring & Logging**: Implement basic monitoring and logging capabilities to track the number of messages processed, any errors encountered, and overall system performance.
6. **User Interface (Optional)**: As an optional feature, consider adding a simple web interface where users can trigger message generation and view the status of message processing.

Your task is to outline the architecture of this mini-application, including the setup of AWS resources through the 'aws-solutions-constructs.aws-lambda-sqs-lambda' package, and provide sample code snippets for each component. Additionally, describe how you would deploy and test this application in a real-world scenario.
