  mklsgridreftri.......determine max circumcircle radii at different iterations
 
  call: [ccrlist,ratios]=mklsgridreftri(gridbase,maxiter,doplot);
 
                      gridbase: (string)
                                this string deterines which grid base is 
                                used. This must be one of the possible
                                values of the .grid_base field of the
                                LOCSMITH options structure (see
                                MKLSDEFAULTS).
                       maxiter: (numeric)
                                maximum number of iterations applied to the
                                grid.
                        doplot: (string)
                                if present, this must be a string that is
                                accepted as plotmode by MKLSGRIDPLOT.
 
  result: ccrlist: (numeric array) [degree]
                   List of the determined circumcircle radii.
                   ccrlist(i) is the maximum circumcircle radius in degrees
                   of the grid after i-1 iterations (the 0-th iteration is 
                   the initial grid).
                   Length is measured as great circle arc length.
 
          ratios: (numeric array) []
                  List of ratios of circumcircle radii:
                  ratios(i) is the ratio of the max circumcircle radius
                  after i iterations ot the max circumcircle radius after
                  i-1 iterations. This list is derived from CCRLIST.
 
  This routine determines how the maximum circumcircle radius of triangles
  in a grid of % specified type changes with iteration, for a specified number of
  iterations. These factors are needed for the grid construction, when the
  number of iterations necesssary to reach a certain spatial resolution has
  to be estimated.
  The grid is iterated step by step until the specified max number of
  iterations is reached, and all circumcircles are evaluated at each
  iteration.
 
  If no output argument is given, the max circumcircle radii are
  written to the screen
