Deleting the experimental code from the main vision branch
also removing unsued import and fixing some commented out code
refactored the code further - we now don't convert to and from
BufferedImage and MultiSpectralImage but rather take a Bufferedmage,
work internally with a MultiSpectralImage.
refactored the code for field detection to use MultiSpectralImages
Removing old findrgb code since it wasn't being used at all
fixed draw crosses - now it doesnt cause null pointer dereferences
refactored the frame grabing code even more - now we print useful info
when we segment the field regions in the 3rd frame. also now we use
drawCrosses instead of the old printing code
changed the code for detecting the blue markers - now works most of the
time
