[IGSTK-Developers] Regression testing

[Andinet Enquobahrie]

Hi All,

I would like to encourage more regression testing in igstk. Results of 
basic smoke tests are often misleading.   For example,  although the 
"igstkCTImageSpatailObjectReadingAndRepresentation" test was passing, 
there was a bug in the Viewer class and the scan was not correctly 
displayed.  With screenshot taking and saving capability, we should be 
able to generate baseline image and set up regression testing for Image 
I/O and viewer classes.  I will be doing that once I have committed the 
new features.
