Spring semester update 12

[akzysk]

Implemented "You Tell Me" when uploading an image. In other words, the system can run an evaluation when an image is uploaded, based on an existing training set. The segments of this image are trained and classified as blood or not blood based on pure majority.

In the samples view, implemented a button to test single samples at a time against an existing training set.

Now, just need to figure out good attributes to get the 3 sample images to test well for the demo.
