C++20 based asynchronous task utility

This is library to be easier to handle asynchronous task, periodic task and the lambda.

• If you need to run tasks concurrently, please use ThreadPool and the Task.

  • As default, the concurrency is based on the platform's maximum concurrency.
  • If necessary to limit to smaller number, you can specify the maximum number of threads by constructor argument.

• If you need to run task periodically, you can use PeriodicTaskManager to run the Task at your specified period periodically.

• If you want to use lambda, you can use LambdaTask. This helps to use your lambda for the above managers.

• If you want to use so called Timer simply, you can use Timer. This helps to use your simple timer use without any noticing the above managers.

• If you want to use Timer as lambda manner, you can use LambdaTimer.

• Please refer to testcase.cpp to know how to use them.
