[SPARK-6428] Turn on explicit type checking for public methods. This builds on my earlier pull requests and turns on the explicit type checking in scalastyle. Author: Reynold Xin <r...@databricks.com> Closes #5342 from rxin/SPARK-6428 and squashes the following commits: 7b531ab [Reynold Xin] import ordering 2d9a8a5 [Reynold Xin] jl e668b1c [Reynold Xin] override 9b9e119 [Reynold Xin] Parenthesis. 82e0cf5 [Reynold Xin] [SPARK-6428] Turn on explicit type checking for public methods.
