v12.1.0

Add normalizeRootUrl

v12.0.0

Add new methods:

* apiReferenceSchema
* exchangesReferenceSchema
* apiManifestSchema
* metadataMetaschema

and rename servicesManifest -> apiManifest

v11.0.0

testRootUrl is now https://tc-tests.example.com. This may cause breakage in tests that expect the old testRootUrl (https://tc-tests.localhost) but should be easy to fix with search-and-replace.

v10.1.1

• Add servicesManifest (#12)
• Add Python (#6) and Golang (#5) implementations
• Give helpful error on empty/missing rootUrl (#11)
