> Currently {{GremlinDslProcessor}} is located directly in the {{gremlin-core}} artifact. This has a few downsides:
> * it pulls a runtime dependency to JavaPoet
> * annotation processing is always on. The compiler will have to scan the classpath to check if {{GremlinDsl}} is used anywhere. I believe this is an additional step that would not happen if no processor was present.
> It's a good practice to place annotation processors in their own artifact. Then users can opt in, in one of two ways:
> * place the JAR in their compile classpath, but not the runtime one (e.g. "provided" scope in Maven)
> * or use the special {{-processorpath}} of javac ({{<annotationProcessorPaths>}} in the Maven compiler plugin config).
> Either way this provides a cleaner separation, the dependencies that are specific to the processing / code generation part are not retained at runtime.
