Cross build Scala 2.12 and 2.11 + Updated Circe

We're now publishing for Scala 2.12 and 2.11. And we've also updated our Circe dependency to 0.7.0.

Thanks to @jhnsmth for doing this work!

Enums now return DecodeFailures

Enums now return DecodeFailure rather than throwing Exceptions. This makes it easier to chain them (i.e. json.as[MyEnum] orElse json.as[String])

MIT licence added + Minor fixes

Minor fixes:

• MIT licence added
• Removed .json files from jar package (only used for testing, so shouldn't be included).

First release

Contains support for:

• Case classes from Json schema object definitions
• Enums (CountryEnums.NZ, CountryEnums.US, CountryEnums.UK)
• Union types (can be Type A or B or C)
• Free form types (values can be any primitive types, such as Ints, Double, Strings, or Seq, Array, and Map[String, _] of those types.
