Use vector by default
---------------------

If you have a good reason for using a specific container, then do so.
Otherwise, ``vector`` is the best choice for most situations.

The cpp standard actually has it written in::

    vector is the type of sequence that should be used by default.

``vector`` is guaranteed to have the following properties:

* lowest space overhead of any container
* fastest access speed to contained elements
* inherent locality of reference (objects near each other in the
  container are near each other in memory)
* layout-compatible with C
* fastest iterators

Examples:

* use vector for small lists
* or really, use vector for anything small
