Steps for Executing Reports
===========================

Steps that are used to execute reports are divided into 5 categories. Each of these categories is available
as a submodule of ``ppc_robot_lib.steps``.

``input``
    Load data from external sources. This can be for example AdWords, Sklik, database, or even more complex logic
    like URL check.

``control``
    Control statements -- currently table deletion and loops over list of managed accounts.

``transformations``
    Transforms tabular data -- filtering, aggregation, computation of new columns etc.

``persistence``
    Saving current state. Currently, no steps are implemented.

``output``
    Output data to Google Spreadsheets. More output options are to come.

AbstractStep
------------

Each step must implement the :py:class:`ppc_robot_lib.steps.abstract_step.AbstractStep` class.
