"""
Class adds functionality to SafeConfigParser to handle included
other configuration files (or may be urls, whatever in the future)
File should have section [includes] and only 2 options implemented
are 'files_before' and 'files_after' where files are listed 1 per
line.
Example:
[INCLUDES]
before = 1.conf
3.conf
after = 1.conf
It is a simple implementation, so just basic care is taken about
recursion. Includes preserve right order, ie new files are
inserted to the list of read configs before original, and their
includes correspondingly so the list should follow the leaves of
the tree.
I wasn't sure what would be the right way to implement generic (aka c++
template) so we could base at any *configparser class... so I will
leave it for the future
