%IECHO Indent echo
%   [IDT,TAG] = IECHO(NAME) is a useful utility which allows function
%   echoes to be indented. The script returns an empty string IDT such
%   that is inserted in front of displayed text. Than you don't need to
%   take care about prompt indenting any more. To change indent
%   spacing set the INDENT variable to the desired value. Default value
%   for INDENT is 11 (characters). This means that 11 blank spaces will
%   inserted in front of the NAME. INDENT may also be set globally.
%
%   Example:
%     [indent,tag] = iecho('FUNCTION');
%     disp(' ');
%     disp([tag,'Some echo on the 1st line.']);
%     disp([idt,'Some echo on the 2nd line.'])
%     disp([idt,'Some echo on the 3rd line.'])
%     disp([idt,'Some echo on the 4th line.'])
%     disp(' ');
