In this exercise, we will be implementing the programming logic in a package deepthought,
which checks whether an input equals to the absolute answer to life, the universe and everything.
We have a constant answer which represents the answer to life, and a function AnswerToLife which checks the user input
and returns a boolean and an error type.
A requirement is also to have a general error ErrCalculation that we can at the same time use in our AnswerToLife function,
and export to be used in other programs of ours.
