User can validate objects against individual schema objects

OpenAPI version
all

Is your feature request related to a problem? Please describe.
Validating the whole response is great in my API tests. But in my unit tests I'd like to be able to validate objects against individual schema objects

Describe the solution you'd like
given an API spec including:

...
components:
  schemas:
    ExampleSchemaObject:
      type: string
...

Be able to do

expect('foo').to.satisfySchemaObject('ExampleSchemaObject') // passes
expect(['foo']).to.satisfySchemaObject('ExampleSchemaObject') // throws useful error 

And to be able to do this with more complex schema objects too

Describe alternatives you've considered
I've not found any other open source packages with this functionality

#42 should support this entirely.

Fyi:

• OpenAPI 3 docs on schema objects.
• this can find schemas defined in the component object of an OpenAPI 3 spec or definitions object of an OpenAPI 2 spec
• this does not support validating objects against definitions of response objects, parameters, security stuff, etc. That should be easy to implement though, so if anyone wants that raise an issue :)
