-I/O
   
   Given:
   
      path      MISR path
      res       resolution in meters
   
   the call:
   
      status = MTK_PATH_TO_PROJPARAM( path, res, proj_params )
   
   returns:
   
      status         0 on success; otherwise failure
      proj_params    IDL structure containing projection parameters
     
-Examples

      ;;
      ;; Set up input parameters
      ;;
      path  = 160
      res   = 275.0
      
      status = MTK_PATH_TO_PROJPARAM( path, res, proj_params )
      
      ;;
      ;; Output... only print out some of the projection parameters
      ;;
      print, 'path                  : ', path
      print, 'resolution (meters)   : ', res
      print, '================================================='

      FOR i = 0, N_TAGS(proj_params)-1 DO BEGIN $
         IF N_ELEMENTS(proj_params.(i)) LE 2 THEN BEGIN $
            nnn = STRTRIM(N_ELEMENTS(proj_params.(i)),2) & $
