DataExamples

A trait for specifying what example data looks like. Differs from the smithy.api#examples trait in that it can be used for any shape, not just operations. Below is an explanation of the different example formats that are supported.

1. SMITHY - this means that the examples will be using the Document abstraction and will be specified in a protocol agnostic way
2. JSON - this means the examples will use the Document abstraction, but will not be validated by the smithy NodeValidationVisitor like the first type are. This type can be used to specify protocol specific examples
3. STRING - this is just a string example and anything can be provided inside of the string. This can be helpful for showing e.g. xml or another encoding that isn't JSON and therefore doesn't fit nicely with Node semantics
