Provide calibration

[wittenbe]

Currently, the Recognizer.cpp has to be changed for a different stream other than Trump's and the program recompiled, requiring the user to be tech-savy enough to do so.
The idea is to encapsulate each streamer's calibration in a separate file as well as provide a tool that automates the calibration process as much as possible.

Some thoughts:

• Make user provide an image of an arena start
• use SIFT features of all classes to find matches in the whole image (very computationally expensive, but ok since it's done once)
• use the matches to calculate a homography
• estimate size of the ROI relevant for phashes, find a local image patch with optimal phash
• ideally/hopefully information about the game's resolution within stream image can be won that away, and other ROIs just require proper rescaling

I'm writing a stats tracker / recognizer in c# at the moment.

I got really sick of debugging / screen capping / photoshopping source images, so I wrote a 'area/phash' designer.

Sorry for the tease ;)

Maybe it helps to get some ideas
