Refactoring/Cleanup

[danielchristopher1]

I decided to take a look through our code. There were some things I noticed that we should probably fix.

• Take out the isAvailable() method out of OpenCVUtils, it shouldn't belong to a util class for OpenCV image processing.
• Probably need more javadocs.
• Code to pull json data from files is messy and over complicated
• Some of our member variables should be put into their base interface/ class.
  Ex:
  private Set set; rather than: private LinkedHashSet set
• We are using alot of linked data structures, thats probably not needed for most cases.
• General cleanup would be nice
