Skala is an extension for scala programming language, providing paired data structures, keyed vectors, etc. Skala package is now ir.angellandros.scala.

Paired iterables are main data structure of skala, and the main reason it has created. Skala is providing some basic tools for working with paired iterables, such as reduceByKey. Keyed vectors are very similar to paired iterables, with the exception that they are well-defined (in a set theory manner), and have ID. ML is another package of skala, providing simple machine learning algorithms based on keyed vectors. Canopy clustering algorithm is an example.
