WrapperClass

Let us unwrap and wrap value in any class that wraps a single value (not only AnyVals)

For a class to be considered wrapper it has to:

• have a public unary constructor
• expose a getter of the same name and type as constructor's argument

Basically, it is a value class without the need to extends AnyVal. This is useful since sometimes we have a type which is basically a wrapper but not an AnyVal and we would like to unwrap it and attempt to derive code as if it was AnyVal. Since it is very contextual, we need to have a separate utility for that.
