Conversion of model to a list
Function converts given model from internal structures in C++ to R's data structures.
The model structure as returned by
The function converts the model referenced by
model from C++ internal structures
to R's lists. Currently it is implemented only for random forests models.
For random forest a resulting list contains first all the information on the forest level, followed by the list of trees. For each tree the nodes are recursively nested with indication of node type (leaf or internal node) and than required information for that data type.
