ToDo List

Approach

[DONE] Never throw an exception from the parser, just add to the errors collection, and try and keep going
..or provide a client parameter (NeverThrow, ThrowIfErrors, ThrowOnFirst)
[DONE] Load components first, or JIT load referenced items
Started. Add validation to model classes, throw exception as normal. Allow parser to catch exception and add to ParseErrors collection

Organization

[DONE] Move parse field dictionaries out of model classes (Still not convinced about this)
[DONE] Move errors collection to parsing context object

Missing features

parse V2 OpenAPI (Need high level understanding of how this is going to work)
[DONE] need tests to show $ref is working.

Nice to have

Add extension parsers
