Contourlines 2D plot
=======================

This demo shows how to display contour lines in an ``itom.plot2``.

The contour levels can be set via the ``contourLevels`` property.
The expected type is a ``dataObject`` of shape ``1 x N`` of type
``uint8``, ``int8``, ``uint16``, ``int16``, ``int32``,
``float32`` or ``float64``. The line width and color map can
be adjusted by setting the property ``contourLineWidth`` and
``contourColorMap`` respectively.
