ImgMath: convenient static methods in ImgMath for invoking compute/into:

RandomAccessibleInterval< FloatType> ImgMath.computeIntoFloat( IFunction )
RandomAccessibleInterval< O > ImgMath.computeInto( IFunction, RandomAccessibleInterval< O > )
RandomAccessibleInterval< O > ImgMath.computeInto( IFunction, RandomAccessibleInterval< O >, Converter< RealType< ? >, O > )
