Create a custom set type.
Sometimes it is necessary to define a custom data structure of some type, like a set. In this exercise you will define your own set. How it works internally doesn't matter, as long as it behaves like a set of unique elements.
This exercise requires you to create custom equality comparison logic. For more information, see this page.
To run the tests, run the command dotnet test from within the exercise directory.
Initially, only the first test will be enabled. This is to encourage you to solve the exercise one step at a time.
Once you get the first test passing, remove the Skip property from the next test and work on getting that test passing.
Once none of the tests are skipped and they are all passing, you can submit your solution
using exercism submit CustomSet.cs
