=====

There are a few important classes which will help you build your DCF.
The ``Company`` class encapsulates three classes: ``BalanceSheet``, ``CashFlows``,
and ``IncomeStatement``. Once a ``Company`` object is created using the 3
financial statements, this can be passed to one of the DCF models (currently either ``SimpleDCF``
or ``DCF``).
