Model Observers

The use of model observers has been used in several places of the app to reduce error for missing mandatory tasks that need to be invoked upon creation/modification/deletion of a model.

It is crucial to know where these are used and what their purposes are, as it is not clear when an observer is being invoked due to it working off of model events (no reference to the observer can be found within the model class itself).

Below are the observers for the models along with what their purposes are.
