This is a simple C++14 source library for creating multiple timer pools, each of which can contain multiple timers with configurable timeout intervals and callback functions.
I've made use of shared/weak pointers to ensure that the timers do not leak and that handles to timers created within a pool do not outlive their parent.
Callbacks are executed on the pool's thread that created the timer. Timer
intervals are specified in milliseconds, based on wall-clock time (using the
standard libraries' std::chrono::steady_clock as the timer pool's timer
reference).
Created timers are weakly bound to their parent pools; if the last user-held reference to the parent pool expires, the pool is destroyed and all child timers will cease to run.
Timers will stop automatically if their last user-held reference expires.
A timer object whose parent pool is no longer valid will not run, however it will remain a valid object and can be safely modified without deadlocks or crashes.
Tested on Visual Studio 2019 (Windows) and Clang/GCC (Linux). Only C++14
standard library and compiler support is required, no special libraries,
although on Posix systems this generally assumes pthreads is available.
