/**
* \class SOMMap
* \brief This class represent a Self Organizing Map.
*
* The Self organizing map (or Kohonen map) is a type of neural networks. It is based on an analogy with
* the visual cortex, where similar inputs activate neighbor neurons.
*
* This class extends the Image object, where each pixel represents a neuron in the map.
* It is templated with a distance parameter used to compute the neuron response to an input.
* Thanks to the extension of the Image object, reading and writing is supported through standard image
* readers and writers.
*
* The training is done via the SOM class, and the activation map can be produced with the SOMActivationBuilder
* class.
