Maps: Parametrized Layer
========================

Build a model of a parametrized layer in a wholespace. If you want to
build a model of a parametrized layer in a halfspace, also use
maps.InjectActiveCell.

The model is

.. code::

    m = [
        'background physical property value',
        'layer physical property value',
        'layer center',
        'layer thickness'
    ]
