Usage: t-focus <focus-level> <additional-sbagen-options-if-required>

Focus levels available, with meaning from Ken E-F, if he mentioned it:
  3	
 10	Brain awake, body asleep
 12	Expanded consciousness - in the mood to head out and explore
 15	No time - 3 hours seems like 2 minutes
 21a	}  Alternate energy systems, bridge into worlds with 
 21b	}    non-human entities.
 22	Place where people with loose, chaotic thoughts go after death.
 23	
 24	Belief system territories - place where dogmatically inclined people
          go after death.
 26
 27	The park - a way-station, a place of high creativity, a stepping stone
          into areas beyond

Note that the focus level tone frequencies and beat-frequencies were
measured, but the relative amplitudes of the tones were not measured,
and may not be correct.  The original tone-sets almost certainly had
some tones stronger than others, but with this script, all have been
given approximately equal audible presence.  This means that these
tone-sets might not work at all like the original ones.  But still,
for experimentation, this is a lot better than nothing, considering
the cost of obtaining Monroe Institute courses !
