''' A configuration dialog for TaurusPlot.
The dialog uses a Model/View design:
- it uses a :class:`CurvesTableModel` for describing the curves
configuration
- it has two views on that model: a :class:`QTableView` and a
:class:`CurvePropertiesView`.
- The selection is managed via a :class:`ExtendedSelectionModel` which is
shared by both views.
It also has a data sources browser which is used to select the sources of
the data to be used by the curves. Currently supported sources are: Tango
attributes, Nexus/HDF5 datasets, and column organized ASCII data. Apart from
this, the dialog allows to use mathematical expression and the given sources
to assign values to the curves
When the changes are applied (eg, when the Apply button is pressed), the
model is used to (re)configure the plot.
