Bayesian model selection for SVM/SVR following Kwok et al. ,


   Proceedings of the European Symposium on Artificial Neural Networks (ESANN), pp.177-182, Bruges, Belgium, April 1999.
   for selecting the parameter C and ranking models
  
   inputs:
     A		    - SVM/SVR
  
   hyperparameters and their defaults:
     use_balanced_C=0  - adapt balanced C for SVM
     type='L1'	      - use l1-SVM
  
   Methods:
    train    - optimizes soft margin parameter for given data
    test     - 
  
   outputs:
     pbest      - best parameter C
     posterior  - posterior probability for the model (given the data)
   Example:
   
    [r,a]=train(bayessel(svm),gen(toy))
    [a.pbest,a.posterior]
