Description

Index type based in flat_map. Just derives from flat_map and defines the interface needed by managed memory segments.

`flat_map_index` public construct/copy/destruct

```
( segment_mngr);
```
Constructor. Takes a pointer to the segment manager. Can throw.

`flat_map_index` public member functions

```
 ( n);
```
This reserves memory to optimize the insertion of n elements in the index.
```
 ();
```
This frees all unnecessary memory.
