amt_disp - AMT-specific overload of the function 'disp'

Program code:

function amt_disp(msg,flag)
%amt_disp AMT-specific overload of the function 'disp'
%   Usage: amt_disp(X);
%     amt_disp(X,'progress');
%     amt_disp(X,'volatile');
%
%   AMT_DISP(X); can be used to show message X in the command
%   window. The output of AMT_DISP depends on the start-up
%   configuration of the AMT. 
%     
%   When the AMT is started in the verbose mode (default mode), AMT_DISP 
%   will always display. When the AMT is started in the documentation mode, 
%   AMT_DISP will display only if no flag is provided. When the AMT is 
%   started in the silent mode, AMT_DISP will never display. See
%   amt_start for further explanation on the start-up configurations. 
%
%   AMT_DISP(X,'progress'); can be used as progress indicator. It will be
%   shown during the normal operation but supressed when used to create the
%   documentation.
%
%   AMT_DISP(X,'volatile'); can be used as volatile progress indicator.
%   Any subsequent call of the AMT_DISP will delete the previous volatile
%   message. This way a changing progress can be clearly shown even in loops.
