  /** @file Filterinst.hh
      @brief inline code for instantiation of filter classes

      usage: define FILTER_INSTANTION_CLASS as your filter class, e.g. 
      #define FILTER_INSTANTION_CLASS Gauss
      Decide whether you want to allow unsigned output, which makes no sense
      for gradient filters, because they might produce negative values
      if you want to prohibit instantiation of unsigned output images,
      #define FILTER_INSTANTIATION_NO_UNSIGNED_OUTPUT
      Do all this in the cpp file of your class implementation and then
      #include "Filterinst.hh"
      which explicitly creates all instances that are alowed by your current
      cmake configuration, e.g. BUILD_IMAGE_SHORT, ...

      WARNING: This class steers the generation of all filter objects of
      BIAS, dont touch this unless you REALLY know what you are doing.
