+To use the validator call the validate function with an instance object and an optional schema object.
+If a schema is provided, it will be used to validate. If the instance object refers to a schema (self-validating),
+that schema will be used to validate and the schema parameter is not necessary (if both exist,
+both validations will occur).
+The validate method will return an array of validation errors. If there are no errors, then an
+empty list will be returned. A validation error will have two properties:
+"property" which indicates which property had the error
+"message" which indicates what the error was
