[IGSTK-Users] Transform Data Export

[Jake McIvor]

Thanks for the assistance.  I have successfully used the OpenIGTLink
examples to send transforms to Slicer on another computer (cool!), and
modified the broadcaster example to export data to a file.  I still
have to do a little debugging as it seems to miss one or two
transforms occasionally compared to what the serial log says.
