% randInt - create random integers.
%
% r = randInt(N);
%   returns a random uniformly distributed integer 1 <= r <= N.
%
% r = randInt([M N]);
%   returns a random uniformly distributed integer M <= r <= N.
%
% r = randInt(M,sz) and r = randInt([M N],sz)
%   returns an array of size sz with random integers.
%
% If sz is a scalar, a square array of size [sz sz] is returned.
