Property auto completion for Orika mapper

Hi,

I'd like to write a small plugin to enable property auto completion for the Orika Mapping Framework.

A mapping usually looks like this:

mapperFactory.classMap(PersonSource.class, PersonDestination.class)
   .field("firstName", "givenName")
   .field("lastName", "sirName")
   .byDefault()
   .register();

`classMap(Class<A> a, Class<B>b)` returns a ClassMapBuilder<A, B> then mapping for fields is defined by invoking the field, fieldAtoB, or fieldBtoA methods. Nested fields can be accessed via '.' eg, field("address.street", "street")

What I'd like to to is to enable auto completion support for the properties of the classes. Since the ClassMapBuilder has the generic type information it should be possible to access that.

In a later stage I'd also like to add support for the advanced "in-line property syntax" https://orika-mapper.github.io/orika-docs/advanced-mappings.html

In-line property syntax:

«name» :{ «getter» | «setter» [ | type= «type» ] }

«name» :{ «getter» [ | type= «type» ] }

«name» :{| «setter» [ | type= «type» ] }
