371 | * To achieve that we need to define the following flags: |
372 | * 0: hasnochildren |
373 | * 1: haschildren |
374 | * 2: is first |
375 | * 4: is last |
376 | * a node has sibling nodes if it's not the last node |
377 | * a node has no sibling nodes if it's the last node |
378 | * By using binary comparations we can store the flag in one var |

380 | * example: |
381 | * -1 par = 0, level = 0, flag = 1 + 2 + 4 = 7 (haschildren, isfirst, islast) |
