/** \class OrImageFilter
* \brief Implements the OR bitwise operator pixel-wise between two images.
*
* This class is templated over the types of the two
* input images and the type of the output image.
* Numeric conversions (castings) are done by the C++ defaults.
*
* Since the bitwise OR operation is only defined in C++ for integer
* types, the images passed to this filter must comply with the requirement
* of using integer pixel type.
*
* The total operation over one pixel will be
*
* \code
* output_pixel = static_cast<OutputPixelType>( input1_pixel | input2_pixel )
* \endcode
*
* Where "|" is the boolean OR operator in C++.
