Allow different entropy threshold queries to be run without using slider widget... #26

Since it was decided the average user will find the slider widget difficult to use for entropy threshold queries, we will need an alternative.

The keyboard is probably a logical starting point. Up and down could toggler the threshold up and down. It would then repeatedly run the entropy threshold query in a loop until it finds a change in the tree structure. It would then stop and show the result. This guarantees that pressing up or down always shows a change. The user does not care about what actual threshold values are used.

We could then add / modify a widget so that they can press up and down buttons in the graphical UI. This will make it consistent with all of the other application controls.

A functional version of this using a widget with two arrow buttons is posted in the master branch now. We could add keyboard support as an additional feature if desired.

We decided to combine the slider widget with this. It is done, for the widget.
