A threadpool library

ThreadPool::ThreadPool(const unsigned int count_threads)

Create a new threadpool with the specified number of threads. Tries to select a reasonable number of threads if the caller does not pass an argument.

ThreadPool::start() -> void

Activates the worker threads. You must start a threadpool before submitting a task to it.

ThreadPool::join() -> void

Waits for the workers to complete all tasks in the queue before joining all the threads.

ThreadPool::submit(Callable &&f, Args &&...args) -> std::future<std::invoke_result_t<Callable, Args...>>

Submits a new task f to the threadpool to be called with args. Returns a std::future to the result of calling f with args. NOTE: When submitting a function template to a threadpool, you need to specify the template arguments or wrap the function in a lambda to avoid compiler errors, since there are issues with using C++17's CTAD here.
