The relevance vector machine for regression by M.Tipping

   Implementations as in SparseLib 1.0
   See : http://research.microsoft.com/mlp/RVM/relevance.htm
   Comments from -gb-:
   Note : So far requires centered data !! 
   Note that if you get an error due to "Bad conditioned Hessian" 
   its an inherent problem in the implementation. Mostly this implementation
   works with rbf and rarely with a linear kernel.
   Furthermore if you try to solve a multivariate regression problem the
   code automatically recognises and you get a multi_reg(relvm_r) object
