[Insight-developers] Tests reworked

[Bill Hoffman]

I have added a feature to the test driver that makes it easier to use
from a debugger.   When you run a test driver with no arguments,
it produces a text menu, and you can select which test to run.

For example:

bash-2.05$ ./itkNumericsTests.exe 
Available tests:
0. itkAmoebaOptimizerTest
1. itkConjugateGradientOptimizerTest
2. itkGradientDescentOptimizerTest
3. itkLBFGSOptimizerTest
4. itkLevenbergMarquardtOptimizerTest
5. itkNumericsTest
6. itkOptimizersHierarchyTest
7. itkRegularStepGradientDescentOptimizerTest
8. itkVersorTransformOptimizerTest
To run a test, enter the test number:
