Description
If one tries to do Integration when the upper limit and the lower limit are within the same bin, one gets a segmentation fault. I tried this on an event workspace (CNCS from autotest), with limits 45000 to 48000. The same result happens if you use a histogram workspace.
Suggested outcome of integration if within the same bin:
- For events use rebin
- For histograms either return 0, or intensity/fractional bin width

Segmentation fault problem is fixed. However, the error in partial bins is different from the rebin result.This will be solved in #5662

The answer for histograms is 2. Intensity / fraction bin width, this is what rebin would do.
