Added JUnit Test for Control Block, instead of just 'printing main'
devtest. IO Testing is left.
Fully Devtested Dag Resolver, works. Partial Unittest for resolver too.
Note that the TestResolveDag uses printing from main to check ALL of the
IO. Manually creating the IO for JUnit is taking way too much time.
Merge pull request #6 from Upsham/dev-ukd

Milestone code for TaskdagResolver. Works fully, dev-tested. Partial UnitTest written.
