<BLOCKQUOTE>Boosting implementation.
As the idea of boosting in regression hasn't been really well tested,
this is boosting for *classification* only.
<P>This trainer will "boost" the machine given by the <TT>WeightedSumMachine</TT>,
on the given <TT>DataSet</TT>.
<P>You have to provide a <TT>ClassFormat</TT> to know how the classes are encoded.
