Add splitters information workspace to SNSPowderReduction

[Peter Peterson]

Since it is created in the reduction gui, it should be used in SNSPowderReduction when splitting workspaces. Normal caveats about it being optional and sanity checked against the splitting workspace apply.

Instruction for verification

Run the script as following:

# Modified from SNSPowderRedux.py

from mantidsimple import *

def getSaveDir():

"""determine where to save - the current working directory"""

import os

return os.path.abspath(os.path.curdir)

# From PG3Analysis(stresstesting.MantidStressTest)

cal_file = "PG3_FERNS_d4832_2011_08_24.cal"

char_file = "PG3_characterization_2011_08_31-HR.txt"

savedir = getSaveDir()

# Generate event splitters

Load(Filename=r'PG3_4844_event.nxs',OutputWorkspace='PG3_4844_Log',Precount='1', MetaDataOnly=True)

GenerateEventsFilter(InputWorkspace='PG3_4844_Log',

OutputWorkspace='TimeSplitters', InformationWorkspace='SplitterInformation', TimeInterval='500', TitleOfSplitters='Even time splitter')

# run the actual code

SNSPowderReduction(

Instrument="PG3", RunNumber=4844, Extension="_event.nxs", PreserveEvents=True, CalibrationFile=cal_file, CharacterizationRunsFile=char_file, LowResRef=15000, RemovePromptPulseWidth=50, Binning=-0.0004, BinInDspace=True, FilterBadPulses=True, SaveAs="gsas and fullprof and pdfgetn", OutputDirectory=savedir, NormalizeByCurrent=True, FinalDataUnits="dSpacing", SplittersWorkspace="TimeSplitters", SplitInformationWorkspace="SplitterInformation")

In the output workspaces with name starting as 'PG3_4844', you can check the title of them with the splitter information workspace to see whether they match.
