Complete TDD-based unit tests

[Echelon9]

• Review and implement Excel-TDD unit tests. See further: https://github.com/timhall/Excel-TDD.
• Write unit tests with base coverage of .Add(), .Test(), .Size() methods for various input types.
• Ensure all tests pass. (Complete TDD-based unit tests #3)

These presently pass for all but one unit test, which relates to the BloomFilter.size() method.

InlineRunner.RunSuite Specs, ShowFailureDetails:=True, ShowPassed:=True, ShowSuiteDetails:=True

= FAIL (1 of 6 failed) = 24/09/2014 11:53:34 PM =========================
X BloomFilter
  + basic bloom filter
  + jabberwocky
  + basic uint32
  + wtf
  + works with integer types
  X size
    Expected -1 to be close to 97.014763
    Expected -1 to be close to 1007.54932

Now that the full complement of unit tests pass, it's time to build a script harness so the testing environment, dependencies and tests themselves can be run with (hopefully) one commandline invocation.

InlineRunner.RunSuite Specs, ShowFailureDetails:=True, ShowPassed:=True, ShowSuiteDetails:=True

= PASS (6 of 6 passed) = 28/10/2014 8:23:53 PM =========================
+ BloomFilter
  + basic bloom filter
  + jabberwocky
  + basic uint32
  + wtf
  + works with integer types
  + size

Post 9d5e6fe a successful unit test run looks like:

InlineRunner.RunSuite Specs, ShowFailureDetails:=True, ShowPassed:=True, ShowSuiteDetails:=True

= PASS (7 of 7 passed) = 9/03/2015 6:22:18 PM =========================
+ BloomFilter
  + basic bloom filter
  + jabberwocky
  + basic uint32
  + wtf
  + works with integer types
  + size
  + FNV-1a hash known collisions
