[Insight-developers] HeadersTest & #ifdefs

[Luis Ibanez]

The HeaderTests files insisted in compiling the deprecated registration
classes. This prevents all the other tests in Code/Algorithms to be run.

In order to avoid that, temporary #ifdef guards were added to the files
that are not supposed to be compiled any more.

They include :

itkImageToImageAffineMutualInformationGradientDescentRegistration.h
itkImageToImageAffineMutualInformationGradientDescentRegistration.txx

itkImageToImageRigidMutualInformationGradientDescentRegistration.h
itkImageToImageRigidMutualInformationGradientDescentRegistration.txx

itkMeanSquaresPointSetToImageMetric.h
itkMeanSquaresPointSetToImageMetric.txx
itkMultiResolutionMutualInformationAffineRegistration.h
itkMultiResolutionMutualInformationAffineRegistration.txx
itkMultiResolutionMutualInformationRigidRegistration.h
itkMultiResolutionMutualInformationRigidRegistration.txx
itkNormalizedCorrelationPointSetToImageMetric.txx
itkPatternIntensityPointSetToImageMetric.txx


The "PointSetToImage" metrics will be reworked shortly...
