Cavataca use case

[bwalsh]

At a high level, the set of data returned from sevenbridges' project::files is different from the set of data from their task::outputs.

For example task.outputs returns a dict, that in turn contains a class == 'File'. The properties are:

{
  "name": "CG0013-3205.FN.vcf",
  "checksum": "sha1$6fb754d4d194783f06c8df29d52e888eb4a9f98d",
  "location": "5a9eadd64f0c37e14fd0c6b4",
  "secondaryFiles": [],
  "path": "5a9eaddd4f0c37e14fd0c6c9",
  "dirname": "/mnt/nosbgfs/workspaces/4eba4c86-03cb-411a-a9a2-45dd6cbde1f8/tasks/d27205a8-3abe-4665-aac5-c3dbde0373b6/root_a_1/output",
  "class": "File",
  "contents": "None",
  "size": 1016592
}

Note: this structure not 'typed' i.e a python class

project.files returns

{
  "origin": {},
  "name": "CG0004-9569.cram",
  "tags": [
    "cram",
    "broad",
    "seidman2016"

  }
}

Note: no checksum

the quantity and keys between these two sets of "Files" do not align
