Added LLBinaryOperators 0.1

Hi!

New podspec. A small helper function for NSArray to assist with binary enumeration. I've been trying to get this building on travis for unit tests, however xctool doesn't seem to find the [main project scheme](https://travis-ci.org/lawrencelomax/LLBinaryOperators#L484). If anyone knows a quick solution to this that would be great.
