print the counter in a form of the table row

       std::string header = "       Counter :: Group         |     #     |";
       header += "    sum     | mean/eff^* | rms/err^*  |     min     |";
       header += "     max     |") ;

       info() << header << endmsg ;

        // loop over counters:
        for ( ... )
         {
          const std::string& name    = ... ;
          const std::string& group   = .. ;
          const StatEntity&  counter = ... ;
          info() << formatAsTableRow ( name , group , counter ) << endmsg ;
         }

The table row for the regular counter is printed as 8 fields

- counter name (string)
- counter group (string)
- number of entries (long)
- overall sum (double)
- mean value (double)
- RMS (double)
- minimal value (double)
- maximal value (double)

The printout is performed according to the format, described in optional "format1" parameter using Boost Format Library. The incredible flexibility of Boost Format Library allows to customize the overall layout of the table form minor change the format of individual columns to the overall reshuffling of the reformatted columns

If the parameter "flag" is set to `true` AND either the counter name or counter group, converted to the lowercase contains one of the substrings: "eff","acc","fltr","filt","pass" AND (of course) the content of the counter allows the interpretation of the counter as the binomial efficiency counter, the printout is performed using 6 fields ("binomial efficiency format")

- counter name (string)
- counter group (string)
- number of entries (long)
- overall sum (double)
- binomial efficiency [perCent] (double)
- uncertainty in binomial efficiency [perCent] (double)

The printout is performed according to format, specified by parameter "format2"

  http://boost.org/libs/format

Parameters:

  | name | the name associated with the counter
  | group | the group associated with the counter
  | counter | counter to be printed
  | flag | use the special format for "efficiency" rows
  | format1 | row format for the regular rows
  | format2 | the special row format for the "efficiency" rows

Returns:
  formatted row in the table
