Cleanup
ArrayTest: cleanup
ArrayTest: added two test cases
build.xml: fixed attribute value spelling

Well, it's more of a brain fart than a misspelling.
Luckily, even this ridiculous value was semantically correct.
AccessorTest: cleanup

- Fixed commenting (added some, removed some, corrected some).
- Renamed constructorArgDisablesSetter test to the more correct
  constructorInitializationDisablesSetter, since use of the constructor
  attribute isn't the issue.
AccessorTest: add two tests
AccessorTest: make TestParameters public

This class is relatively special-purpose, but it's useful in
several tests, so it should be accessible to them to enable reuse.
Added SparamTest
Added ValueConsistencyTest
