Mindmap updated

I updated the mindmap for my FTIR touch screen project. It can be found here. I added a couple new links and some info. I started work on the software end. I was going to drop using OpenCV's Blob detection library since it didn't seem to be working correctly. However, I happened to glance over the docs for it and I realized what my problem was - the blob tracking lib expects greyscale input and I was feeding it color input. With that change in place it seems to be working well. This should save me some work but I still need to write some code for tracking blobs from frame to frame to ensure that they are recognized as being the same blob.
