Make Slicer Parameters box non-modal and add it to the Tools menu

[pkienzle]

The Slicer Parameters box is modal. This means that you can't interact with the help window while the Slicer Parameters box is displayed.

Making the box non-modal has some good UI benefits. E.g., you could interact with the slicer parameters from the graph as well as typing in the numbers in the box. You could put the slicer in the Tools menu where it is easy to find rather than having to select a slicer on a graph before the user even knows the slicer box exists. You could also make slicing available to data sets that are not currently plotted, which may be useful for batch slicing.

Am raising the priority of this, as it is irritating!

The batch slicing widget looks pretty restrictive. How about two separate actions with two different widgets?

1. The 4.1 (also current 5.0) Slicer Parameters widget accessible from the context menu of 2D plots with only slicer parameters. Basically reverting to 4.1
2. Additional Batch Slicing widget, accessible from the Tools menu. This one would be a variation of the current (4.2) batch slicer with functionality as described above. Since the slicer is going to act on a number of datasets, we probably need to display one of them to visualize the slicer extent?

Modality is a non-issue, the current Slicer Params widget in 5.0 is non-modal

This seems like a reasonable approach to me. A question is whether this is a GUI function or a sascalc function that the GUI visualizes. As @kienzle suggests, there might be a reason for a script to want to use the slicer to generate 1D plots that are then fit by a model etc. As I think about it I think that is correct. The function of the slicer is not really a GUI function per se?

Second question: since the modal issue of this ticket is resolved in 5.0 should we generate a new ticket for the above issues (splitting functions, ensuring that it is all in sascalc) or are those essentially already done anyway in which case we can just close this ticket.

Will leave this open for now as a reminder we need to maybe add a new ticket. As soon as the questions are answered this ticket should be closed I think.
