changed version number to 0.9
representer-version is now considered when writing the itkVectorImageRepresenter
- corrected some issues for compilation on OpenSuse

- updated part of the interface for itk wrappers
- Added an itkImageROIRepresenter, which enable to mask out background pixels from the statistical representation (setting a binary mask together with the reference sample)
- TODO: add a test for the new itkImageROIRepresenter
added an example to test that the new itkImageROIRepresenter.h works.

(updated .gitignore which would otherwise ignore all files beginning with build (in particular, the examples) )
finished testing, improved documentation and cleaned the code
finalization of the example buildImageIntensityModelOnROI
fixed wrong method call in ComputeCoefficientsForPointValues
adapted python wrapping to reflect new method name StatisticalModel::ComputeCoefficientForPointIDValues
adapted python tests to reflect new method name StatisticalModel::ComputeCoefficientForPointIDValues
added support for leave-one-out cross-validation.
fixed a bug in the Conditional model generation...

Now, the conditioning information is also saved in the modelInfo
Fixed a bug in the ConditionalModelBuilder.h
