Add statistic information on GetDetOffsetsMultiPeaks()'s reuslt

[Wenduo Zhou]

GetOffsetsMultiPeaks are going to modified to improve performance on calibrating powder diffractometers. The code should be refactored in order to make it convenient for future modification.

Its wiki should be improved for developer/user to understand better how this algorithm works.

The output information table workspaces should be ordered with spectrum indexes. If one spectrum does not have offset calculated, then the peak fitting result of this spectrum should not be added to PeakOffsetTableWorkspace,

It is convenient to add some statistic summary such that we can have a better view to tell whether new FitPeak/FindPeaks improve the performance of this algorithm.

For tester

The major purpose of this ticket is to refactor the code and improve the output information about fitting.

1. Check out branch feature/8601_getdetoffsets_more_stat;
2. Run the the script as below """ CalibrateRectangularDetectors(OutputDirectory = savedir, SaveAs = 'calibration', FilterBadPulses = True,

GroupDetectorsBy = 'All', DiffractionFocusWorkspace = False, Binning = '0.5, -0.0004, 2.5', MaxOffset=0.01, PeakPositions = '.6866,.7283,.8185,.8920,1.0758,1.2615,2.0599', CrossCorrelation = False, Instrument = 'PG3', RunNumber = '2538', Extension = '_event.nxs') """

Data can be found in system test;

3. You can find some statistic on the fitting result reported by log in notice level;
4. Check the output information table workspace. You can find that the rows are ordered by spectra's workspace indexes;
5. In the PeakOffsetInformationTableWorskpace, you can find that some spectra are missing. These spectra that are actually masked.
