• populate `where' slot in `mob' objects.
• `mob_control' now has an `na.action' argument
• cforest with replace = FALSE, fraction = ... can now deal with weights (spotted by Carolin Strobl )
• interface to LAPACK (`dgesdd' for computing a SVD) directly. As a side-effect, the svdmem class can be simplified and no memory allocation during tree growing is necessary (which results in a measureable performance gain)
