Run validation by specifying a single suite name

[jennet]

At the moment the implementation of suite files / suites / imports is a bit confusing.

The import key has potential, but we need to be able to specify a single test suite from a file, so that it runs just that test suite and any suites it imports.

e.g.

{
  :suite1 ["test1.sparql"
           "test2.sparql"]
  :suite2 ["test3.sparql"]
  :suite3 ["test4.sparql"]
  :suite4 {:import [:suite1 :suite2]
           :exclude [:suite1/test1]
           :tests [{:source "test5.txt"
                    :type :sparql}]}
  :suite5 {:import [:suite2 :suite3]
           :tests [{:source "test6.txt"
                    :type :sparql}]}
}

I want to be able to run just suite4 or just suite5, not every suite in the EDN file
