Document how to use this plugin to validate RAMLs

[tadhgpearson]

This plugin seems really useful, but to start with, I would only like to use it to validate that the RAML files are correct, rather than actually generating sources. The provided documentation doesn't show how to do this :(

Hi, if you only need to parse and validate the RAML files then you might find the Java raml-parser useful (although it's not a maven plugin). We use it internally and it can be found here: https://github.com/raml-org/raml-java-parser
