Purpose

It is a Jupyter Widget intended for the visualization of the interactive phase-plane.

It provides sliders for setting:

 The value of all parameters of the Model.

 The extent of the axes.

 A fixed value for the state-variables which aren't currently selected.

 The noise strength, if a stochastic integrator is specified.

and dropdown lists for selecting:

 Which state-variables to show on each axis.

 Which mode to show, if the Model has them.

Entering the coordinates in the X,Y Coordinate Boxes will generate a sample
trajectory, originating from the coordinates entered.
