Nullable fields

[ashenriques]

I'm currently using RichRelevance in my app written in Kotlin.
For that reason I'm having some warnings, since the fields and methods inside you're library are not annotated with "@nullable" when it's the case.

So all my validations in android like "something!=null", where I know for fact that can return either true or false, the IDE always warns that the condition is always true, when in fact it isn't.
