// \brief median filter with circular element
//
//   vepl1_median filtering is an operation that replaces a pixel with the
//   median value of its surrounding pixels, in a certain neighbourhood.
//   Here, the neighbourhood is circular, with an arbitrary (float) radius,
//   which is to be passed to the constructor.
//
//   Note that the function operator>(DataIn,DataIn) is being used; for
//   non-scalar data types (like colour pixels) an appropriate ">" function
//   must thus be supplied.
//
//   Note also the implicit use of DataOut::DataOut(DataIn),
//   which you probably will have to provide when DataIn and DataOut
//   are not the same type.  It could even be argued that these types should
//   always be the same!
