ExDM Delegates, events and anonymous functions sample code harmonization

[mpostol]

Describe problem

Event Examples must be consolidated and harmonized with the delegate examples.
The examples must be consistent with the Programming in Practice - Delegates and Events
The examples must be consistent with the Anonymous Functions sample code.

Describe the solution you'd like

The sample code related to delegates, events, and anonymous functions must be moved around and improved. Consider the many-to-many multiplicity scenario (the same method and += operation in the test project).

Improve the ExDM Udemy script accordingly.

Describe alternatives you've considered

1. Create an independent class and move examples related to it to this class
2. Consolidate examples in the existing DelegateExample class
3. Consolidate examples in the existing AnonymousFunctions class

List of tasks to be accomplished

• TBD

Notes

The issue must be solved after finishing or simultaneously with the progress on Anonymous Functions.
