Using custom features name ?

[leow193]

Hello,

I was looking at the code of TREPAN and it would look like it is possible to give custom feature names for the tree in order to replace the "test x[4] > ..." by the actual name of the characteristic use (here, the one for x[4])

But I seem to have failed to do so... Could you please tell me where I should add the feature names in order for them to appear on the trees ?
