LevelInfo

java.lang.Object
- org.apache.directory.mavibot.btree.LevelInfo<K,V>

```
public class LevelInfo<K,V>
extends java.lang.Object
```
A class to store informations on a level. We have to keep :
- The number of elements to store in this level
- A flag that tells if it's a leaf or a node level
- The number of pages necessary to store all the elements in a level
- The number of elements we can store in a complete page (we may have one or two incomplete pages at the end)
- A flag that tells if we have some incomplete page at the end
