/*
Observers
---------
(public member function) - joinable - checks whether the thread is joinable, i.e. potentially running in parallel context

(public member function) - get_id - returns the id of the thread

(public member function) - native_handle - returns the underlying implementation-defined thread handle

Operations
----------
(public member function) - join - waits for a thread to finish its execution

(public member function) - detach - permits the thread to execute independently from the thread handle

(public member function) - swap - swaps two thread objects
