wrapResources

Given the output resources produced by generateResources, merges them into a single resource which complies with com.quarkdown.core.pipeline.Pipeline.execute's output type.

Wrapping can happen by:

• Grouping the resources into an com.quarkdown.core.pipeline.output.OutputResourceGroup (e.g. HTML output).

• Selecting a single resource from the set (e.g. PDF output).
