* Adding first draft of Sets Use IsMember now Using IsMember as backend for Set Non-const validator backend Move set tests to set Clearer inits * Drop shortcut Tighten up classes a bit for MSVC Check with GCC 4.8 too * Simpler templates, but more of them Dropping more type safety for older compilers Shortcut string set * Adding shortcut init Making g++ 4.7 docker image happy Fix Clang tidy issue with last commit Adding one more shortcut, adding a couple of tests * Dropping dual pointer versions of code * Smarter shortcut syntax * Adding slighly faster choices * Cleanup to make InMember simpler * Drop choices for now, adding some tests * ValidationError is now always the error from a validator * Support for other types of initializer lists, including enums * Factor out type utilities, single version of IsMember code * Adding a few tests for #224 * Minor cleanup for Validation Error * Adding tests, moved deprecated tests * Docs updates
