Consolidation\OutputFormatters\Validate

Provides a default implementation of isValidDataType.

Formatters may implement ValidDataTypesInterface in order to indicate exactly which formats they support. The validDataTypes method can be called to retrieve a list of data types useful in providing hints in exception messages about which data types can be used with the formatter.

Formatters may implement ValidationInterface in order to indicate whether a particular data structure is supported. Any formatter that does not implement ValidationInterface is assumed to only operate on arrays, or data types that implement SimplifyToArrayInterface.
