This simple class helps with using SUBPLOT(M, N, P) by showing the SUBPLOT grid
that will be created. The user can interactively choose the grid tiles that should
be used for each axes by brushing the displayed rectangles. The property 'p' then
holds a two-column matrix where each row is the P-input to each axes in the
SUBPLOT for the respective grid part.

Example:

% 1) open the GUI
m = 4; % rows
n = 6; % columns
sbh = subplotHelper(m, n); % open grid tile chooser

% 2) Interactively choose which tiles should be used for subplots

% 3) Retrieve the subplot arrangement matrix:
% Either by copying it to the clipboard (via the button in the GUI) or by calling this:
p = sbh.p;

%% Workflow for subplot arrangement:

% 1) Define subplot dimensions
m = 4; % rows
n = 6; % columns
sbh = subplotHelper(m, n); % open grid tile chooser, choose layout
p = sbh.p; % get subplot arrangement matrix

% 2) Use the matrix for your subplot
x = -5:0.1:5;
for iP = 1:size(p, 1)
ax = subplot(m, n, p(iP, :));
plot(ax, x, sin(x)+randn(size(x)));
end

% 3) Optional: Adjust subplot layout
% show layout again and adjust the tile arrangement using the GUI table
sbh = subplotHelper.showP(m, n, p);
p = sbh.p;
% Then go back to step 2, applying the adjusted layout
