First I jumped on replacing both jscs and jshint with eslint but it might be premature decision. Although linting with eslint is possible (like in there is wikimedia config for eslint) it is still not clear should it But in case the change happens we will be ready. Apart from config stuff this changes few bits spotted by eslint: improves some indentation, removes weird spaces, completes some doc blocks, changes IIFE forms in tests. These changes do not seem controversial. Change-Id: I9f8bf0f5745da8e662685f4cd879ea4baa609c01
