The text input object creates a control window where the user can
enter multiple lines of text. The text is given out in a string output variable.

As the text input does not create threads it must be combined with
other elements, for example a button, which creates the thread for
reading out the object, or its must be read out just when the text
data is needed. Use the mouse to make the control window on the viewer
panel as big as it is needed.
