    function t_begin(num_of_tests, quiet)
%T_BEGIN  Begin running tests.
%   T_BEGIN(NUM_OF_TESTS, QUIET) initializes the global test counters,
%   setting everything up to execute NUM_OF_TESTS tests using T_OK
%   and T_IS. If QUIET is true, it will not print anything for the
%   individual tests, only a summary when T_END is called.
%
%   Example:
%       quiet = 0;
%       t_begin(5, quiet);
%       t_ok(pi > 3, 'size of pi');
%       t_skip(3, 'not yet written');
%       t_is(2+2, 4, 12, '2+2 still equals 4');
%       t_end;
%
%   See also T_END, T_OK, T_IS, T_SKIP, T_RUN_TESTS.
