encoding

xmlite uses very simple Pathfinder inspired hierarchy encoding, consisitng of sequential numbering of tree nodes along with the node depth level, like in the following sample:

    0   1   2
    ----------------------
0|  Module 1
1|      Const 1.1
2|      Function 1.2
3|          Argument 1.2.1
4|  Module 2
5|      Function 2.1

Should be encoded into the node-type and node tables as follows:

Type, Name
---------------
    1, Module
    2, Function
    3, Argument
    4, Cosnt

Index, Level, Type
------------------
    0,     0,    1
    1,     1,    4
    2,     1,    2
    3,     2,    3
    4,     0,    1
    5,     1,    2
