Summary: Added the the tested code for KNN, which was tested and validated in Eclipse for Java Development.

Done: Program created an array of Objects, which serves holds hardcoded accelerometer values.
      It then applies the shortest distance and finds the KNN, and stores it in a next array of Objects.
      Classification is then done, as for each activity do a count of how much time it is present for that
      given KNN neighbour for a given TrainingData. This is done in a for loop for each Training Data

Things to do: The main function still is inside. this must be removed. And the code needs to be integrated
              with the previous code
