Code Style

1. Don't write explicit synthesizers (Use the new LLVM 4 auto synthesizers)
2. If you have a readonly property, write an explicit synthesizer prefixing the generated ivar with double underscores ()
3. Use of curly braces
4. Curly braces should be on a new line for methods
5. same line for conditions and loop structs
6. IBOutlets should always be in a private category inside the implementation file. .h file should be clean and expose only properties that can be set by the calling code.
