And added Fixed/Moving image interfaces

ComponentSelector

The ItkSmoothingRecursiveGaussianImageFilterComponent is templated over
the dimensionality and pixeltype of in- and output. Stings "Dimensionality" and
"PixelType" are added as Criteria to select the right Component.

- Automatically write pixel type and dimension to parameter file from
image type at runtime
- Default parameter maps
- Lots of fixes

Blueprint::ParameterMapType

and cxx files

Interface related criteria can be handled in the MeetsCriteria in the
BaseComponent as well as the iterator over criteria, other (developer-user) specific Criteria are deligated to
MeetsCriterum per iteration.

All example components have the propertie ClassName as selection
criterium.

Moved ComponentSelector classes to ComponentInterface, moved Examples to
ComponentExamples. Made all Examples adhere to ITK factory functionality.

- Changed to namespace selx
- Combined componentbase classes and based it on itkLightObject
- Initial combination of example components
- Made templated ComponentFactory to replace all specific factories
