SafeConfigParser is very similar to the currently used ConfigParser but
it supports interpolation. This means values can contain format strings
which refer to other values in the same section, or values in a special
DEFAULT section. For example:
[My Section]
foodir: %(dir)s/whatever
dir=frob
would resolve the %(dir)s to the value of dir (frob in this case). All reference expansions are done on demand.

Improve documentation about what CustomConfigHelperMixin does,
it was not very clear without a close look to the code before.
