Facilitates easier testing by allowing injection of custom `CoroutineDispatchers` into classes, offering a flexible approach to managing coroutine dispatchers for various environments.
Referencing Coroutine Dispatchers within a class makes testing difficult which is why passing the CoroutineDispatcher via
constructor arguments is a wise decision. component-coroutines' CoroutineDispatchers interface serves as a wedge that points to
whatever dispatcher you set it up with.

CoroutineDispatchers Example (Using Android ViewModel + Hilt)This project utilizes git submodules. You will need to initialize them when cloning the repository via:
$ git clone --recursive https://github.com/05nelsonm/component-coroutines.git
If you've already cloned the repository, run:
$ git checkout master
$ git pull
$ git submodule update --init
In order to keep submodules updated when pulling the latest code, run:
$ git pull --recurse-submodules
