function N = counterinc(name)
% COUNTERINC - Increase counter and return new value
%  
%   N = COUNTERINC(NAME) Increases the counter specified by NAME, and
%   return its new value. If NAME is omitted, the default 'gccounter' is
%   used.
%
%   The counters are read from the matlab preference
%   'counter_utility_data'.
%
%   Example: 
%       counterinit('MyCounter');
%       counterset('MyCounter', 4);
%       counterinc('MyCounter');
%       disp(counterval('MyCounter'));
%   Initializes a counter and sets the value to 4. The counter is then
%   increased by one, and the counter value is displayed.
%

%   COUNTERLIST and COUNTERDELETE
