Version 0.9-13
- update `mvt.f'
- improve the memory footprint of RandomForest objects substancially (by removing the weights slots from each node). More careful revision of the predict and fitting code is needed.
- predictions for cforest with multivariate response are now returned in a matrix (should be a data.frame)
- remove confusing `no admissible split found' warning (which simply meant that the `minsplit' wasn't met).
