• Accept Functions as Input (#97) by @AutoSponge
  Spected now also accepts a function as input to validate against.

const verify = validate(a => a, a => a)
const validationRules = {
    name: nameValidationRule,
}
const input = {name: 'foobarbaz'}
const result = verify(validationRules, key => key ? ({...input, [key]: ''}) : input)
deepEqual({name: ['Name should not be empty.']}, result)
