	This class implements the K-Nearest Neighbor classification algorithm (http://en.wikipedia.org/wiki/K-nearest_neighbor_algorithm). KNN is a simple but powerful classifier, based on finding the closest K training examples in the feature space for the new input vector. The KNN algorithm is amongst the simplest of all machine learning algorithms: an object is classified by a majority vote of its neighbors, with the object being assigned to the class most common amongst its k nearest neighbors (k is a positive integer, typically small). If k = 1, then the object is simply assigned to the class of its nearest neighbor.
