doSSBTest()

int doSSBTest	(	int	argc,

	)

Applying HT twice to a real valued signal f(t) will produce a delayed version of -1 * f(t + d) at its output.

The HT module's complex result, should be (a + ib) = f(t + d) + i * -1 * f(t + d). Therefore, we should see that (a + b) == 0 and (a - b) = 2a.

In this test, we accumulate a histogram of the error magnitude (b + a) – this should ideally be 0.0;
