Feature/pde 427 update decider archetype

I updated the seqware-archetype-decider to reflect PDE advancements including a main method, a jar-with-dependencies. The archetype now asks for the package and workflow-name and uses that to construct the decider class name. the artifactId defaults to "decider-${workflow-name}". The decider class name defaults to ${workflow-name}Decider. There is more documentation in the decider to assist with development. I also updated the documentation to reflect the new archetype.
