class_docstr: Factory that creates concrete initializers for factory centroids.
  
  To implement a custom one, inherit from AbstractCentroidsInitialisation
  and implement all the required methods.
  
  After this, update CentroidsInitialiserFactory.__initialisers hashtable to
  reflect new methods available.
