Clean up ID test to make it a nicer example.
Move all examples test outside the example folder.

It's an actual test and not just a demonstration of
the framework.
Move ID comparison to IdTestResult.

It's a nice example of reuse.
Initial support for external tests.
Clean up imports.
Clean up External ID test example.
Add testData method in main examples test.

The test data is always fetched and computed in the same way for
examples tests so it makes no sense to do it seperately in each
test.
Clean up documentation in ParseTcAllExamples
Standardize naming of test superclass

We now have ParamStandardTest, ParamExternalsTest and
ParamExamplesTest.
