Multiple return types

This is something that is used a great lot in functional programming and can be seen in packages such as fpdart. The main drawback is chaining multiple requests but that we can fix it by also utilizing try-catch.

Our flow

• Repository (Will do try-catch)
• Service (Will also do try-catch but then wrap the results with a Success value and a Failure value)
• Controller (We will now, with compile safe code handle either the Success or Failure value)
