These functions create and free various structures.  Technically, it is
good programming practice to free the structures after using them, although
this is not done in any of the example code. <p>

KLTCreateTrackingContext() is a little different from the other creation
routines in that it uses default values defined 
in <code>klt.c</code> to set up the structure.  
These values can be changed if desired.
