Adds require 'spec_helper' to the beginning of the code examples in README. See more reasoning at #581. I know it seems a bit like unnecessary repetition of code, but it should help prevent developers from copying test outlines from the documentations and getting cryptic error messages as to why the test won't function.
Include require 'spec_helper' in README code examples, fixes #581
