Detailed Description

Define template class policies for ordering the data in a vector.

The aim of this part is to write algorithms which are independent of the internal ordering in the vector.
If later, for efficiency reason, a reverse ordering is preferred for some of the indicators
everything should work the same.

2 class templates:

• VecChronologic : data stored in a chronological order
• VecNoChronologic : data stored in a non-chronological order

Define functions for always getting chronological or non-chronological iteration
Assuming than the vector is initially stored correctly (at its creation usually), a template class policy makes easy to:

• Iterate in a chronological or non-chronological order
• Access the first and last (chronologically) data
• Reorder the vector if it is needed by a specific algorithm
• Append new data, after an update for instance, independently of the internal ordering of these new data

Because they are templates, many operations are checked at compile-time.
For instance there is no need to revert the data of a vector (costly operation), if the order is already correct.

In sending iterators to the vector, it could be used with a list as well ?
Maybe, could return an appropriate iterator : begin_chrono
