%function p = plot_grid(grid,params)
% plot method for a cubegrid. A line plot is performed.
% Text can be plotted in the leafs of the grid.
%
% p is the list of handles to the graphics primitives
%
% optional params:
%   color : RGB vector
%   shrink_factor: if this flag is given, the elements are plotted shrinked
%   plot_level:   if this flag is nonzero, a level plot is performed
%   level  : this integer must be specified in case of level-plot    
%   plot_patch    : if this flag is set (only 2D and 3D) the plot is done
%                   by colored patches
%   axis_equal    : if this flag is set, set axis to equal scale
%
%   leaftext      : vector of strings. Length must be equal to number of
%                   leafelements. The text is shown in the cogs (center of
%                   gravities) of the leafelements.
