-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
