Add support for Galaxy dataset collections

[hackdna]

Multiple dataset processing is implemented by workflow expansion from templates in Refinery. Galaxy now supports this internally via dataset collections.

• Add WorkflowTool method to create collection descriptions, and the collections themselves regardless of nesting depths (addressed by Scottx611x/dataset collection updates #1980)

  • See : OO approach to this here

• Retrieve output after DSC -based Workflow runs and reassociate with their respective Refinery Dataset

Love this idea, let me know if there is anything I can do on the Galaxy/bioblend side to help :).

Thanks John. We'll probably need some help once we start development.
