mongoose-to-swagger

Fixed bug w/ mixed handling.

• Added deep object & nested scalar / schema support.

This is technically a breaking change from 0.x versions since previously:

new Schema({
  foo: { bar: String },
})

would result in a swagger output of "foo.bar": { type: "string" } which is valid swagger, but technically incorrect. Now it will result in { foo: { properties: { bar: { type: "string" } } } } which is both valid swagger and has the desired output.

• Added arbitrary meta field support - common ask was to add arbitrary props like "description" to mongoose schemas and have information propagate out through swagger schema.

• Added better support for "required" fields.
