Hi,
This is a PR for adding the knn algorithm as builtin function. There are two
new builtin functions, namely "knn" and "knnbf".
In order to compare the prediction matrix, we've added a new comparison
method to the TestUtils.
Note that the "knn" builtin is also based on a bruteforce approach.
The reference R script requires two packages ("FNN" and "class") which are
installed inside the RScript.
Thanks for review :)
