Reynold Xin 4137f769b8 [SPARK-8752][SQL] Add ExpectsInputTypes trait for defining expected input types. ... This patch doesn't actually introduce any code that uses the new ExpectsInputTypes. It just adds the trait so others can use it. Also renamed the old expectsInputTypes function to just inputTypes. We should add implicit type casting also in the future.
