Using annotation processor

Have you considered having an annotation processor that can be used for the generator?

I think that it can be done without any direct dependency on AssertJ in the sources. The supported annotation can be some user defined annotation that would be found via an SPI, the configuration parameters can be controlled via APT options.

I haven't looked at the code, but I assume that the entire logic is in here, the [maven-plugin](https://github.com/joel-costigliola/assertj-assertions-generator-maven-plugin) just passes the options to the generator that does everything.

Is this something that would be interesting for the generator?
