RandomTree* Impala::Core::Feature::Read	(	RandomTreeTable *	table,
		int &	index
	)

Call with valid table and the index of the position in the tree where the tree starts (0 for example).

When the function returns index point to the part of the table after this tree. So to retrieve all trees in the table, keep reading RandomTrees from it untill index == Size().
