QA/QC Components
****************

.. note::
    In object-oriented programming, the open–closed principle states software entities
    *(classes, modules, functions, etc.)* should be open for extension, but closed
    for modification. Such an entity can allow its behaviour to be extended without
    modifying its source code. See also: https://en.wikipedia.org/wiki/Open%E2%80%93closed_principle

The QA/QC components combine base components to complex components. They cache the
results and have a specific behavior. To ensure that new QA/QC components can be added,
they all inherit from the abstract base class **autom8qc.qaqc.base.QAQCComponent**. The
abstract class has the abstract method *perform* and the property *results*.
