Stefanie Tellex <http://web.media.mit.edu/~stefie10> has kindly contributed
these two patches for the Camshift Wrapper. The first, camshift.struct.patch,
adds a struct to maintain state. This allows multiple trackers to run at once.
The second patch, rangeChecks.patch, adds out-of-image checks. You may want
to apply it if you find that Camshift Wrapper crashes when tracked objects
go out of frame. On my system (XP + the precompiled 1.0 libraries), it's
not needed, but Stefanie found she did need it.
