reification based on examples

[Benjmhart]

Would be great to automate the schema creation - even if it's crude at first, as a developer tool.

Admittedly, in many cases this may be an anti-pattern, however it can quickly aide in the creation of a schema - particularly when working with poorly documented API's, or when building parsers on one side of an integration, which must agree with an existing implementation.

Ideally i see this as a function [JSON] -> Schema, which can then be rendered out to a file.

Even if this is just the primitive assignments without any fancy string subtypes or other features, it should be reasonable to generate a schema which would fit all provided examples, Quickcheck could assist this process using existing Gen a -> [a] functions.

the rapid development advantages here could make this a great utility, even with appropriate warnings that the schema itself should be treated as the source of truth.
