Slice renderer window: Display data value and measure distances.

[mlavik1]

Changes to slice renderer window:

• Added 3 input modes:
  • Move: Move the plane:
  • Inspect: Select a position by clicking, and display data value.
  • Measure: Click and drag to measure distance between two points.

This should resolve #145

TODO:

• Fixed slice view size? (just clamp it instead).
• Clean up the buttons / UX for adding/removing/switching planes.

@Karthikarc115 does this work for you?
Just check out the "slice-measure" branch, load a volume and go to "Volume rendering" -> "Slice renderer" and click "Add plane".
Also remember that you might need to do some changes to make sure the displayed values are correct, as I mentioned here: #125 (comment)
I'm going to add a setting fort that soon.

Update:
Slice view now looks like this:

Has buttons for adding XY, XZ and ZY planes as well.

Click this button and then click+drag mouse to measure distance:

And I've pushed another change, so the measured distance is shown in the correct units.
You can ignore what I said about having to remove that "/ maxScale" in the code.
You should now be able to simply import a dataset, open the slice rendering window, add a slice and measure the distance.

Hope that works for you @Karthikarc115
