Add debugging info to CODA placement check.

The measured locations and orientations are output to the debug window,
where they can be copied to be used in the scripts.
Simulate CODA placement.

CODA unit placement is simulated in a way that depends on what was the
configuration of the system (upright or supine) when the alignment was
performed.
Added control of reference marker visibility to the GUI.
Simulate errors in the alignment of the CODAs.
Generic installation task.

Guide the operator through the steps of putting the hardware in to the
right configuration and then performing the tracker alignment. The
routine parses the command line to see if it should be done in the
upright or supine configurations and tailors the messages and
parameters accordingly.
