I think it looks pretty good. We just have to add the documentation and
alter the online help. You can take a look at the `pivot.sql_in` file (or any
other function) as an example for the documentation. Let us know if you cannot
compile the docs, it might require the use of a different version of the gcc (I
use gcc 4.5).

> k-Nearest Neighbors is a simple algorithm based on finding nearest neighbors
> of data points in a metric feature space according to a specified distance
> function. It is considered one of the canonical algorithms of data science.
> It is a nonparametric method, which makes it applicable to a lot of
> real-world problems where the data doesn’t satisfy particular distribution
> assumptions. It can also be implemented as a lazy algorithm, which means
> there is no training phase where information in the data is condensed into
> coefficients, but there is a costly testing phase where all data (or some
> subset) is used to make predictions.
> This JIRA involves implementing the naïve approach - i.e. compute the k
> nearest neighbors by going through all points.
