implementation of support for REST method return type overriding (solves not generating models for javax.ws.rs.core.Response)
all Model Properties have required=true by default now which means it doesn't show as optional in swagger-ui
(this commit doesn't cover fixing junit static json files to have that flag set on)
Model fields description added.
It's based on 1) javadoc of a class field or 2) @return portion of javadoc for a getter method. Javadoc from #someValue field will take precedence over a @return javadoc portion of #getSomeValue() method. Note: by default doclet may be run without -private option which will result in skipping all the private fields and methods - in that case it's better to document the model in getter methods.
