  * KernelPCA class is the main class that implements several spectral methods

  * Most of them share an affinity (proximity) )matrix that is computed
  * with the dual-tree all nearest algorithm. All these methods share
  * this affinity matrix and then define their own kernel matrix based on
  * that. Only distance kernels are supported, kernels that are f(distance)
