||This is realized by CART and ID3. It is not difficult to write a new method, because the ancestor DecTreeMethod provide a very comfort framework.
||This is realized by DecTreeMethod.Build and by BuildSpecific of the concrete algorithm.
Preparing of data:
1. Add column with column number (working information) to the chosen table. (The table is already chosen by DecTreeDataBuild dialog).
2. Initialize this column with value 1 - first node - root.
Checking some prerequisites according to a concrete algorithm.
