Added MatHelper. Added ThresholdHelper. Modified ImgHelper to also provide
Mat objects. Fixed issue with Mat always being shades of blue, had to do
with BGR instead of RGB format for the mat. Added resourcePath in
resourceHelper. Modified imagePlayzone to try to do new things with the
thresholding. Wrote a small "edge" detector, more like a "where does the
color Drastically change" kinda detector. " Added threshold playground
whenever I want to consolidate things in ImgPlayzone into that place. 
