Add Reference
=============

R2T2 works by decorating functions, classes or methods where particular
algorithms described in a paper are implemented
or data stored in a repository is used.
General execution of code silently passes these decorators,
but remembers how and where they were called.
The decorators include a short description of the thing being reference,
and the reference itself in any sensible format.

    :language: python

Several references can be added by stacking multiple ``@add_reference``
decorators.
