Stitch1DMany 3 fold overlap.

[Owen Arnold]

Tim is going to pass me a real life failure example. In the mean time I tried this out (see below) and it seemed to work OK for my test case:

import numpy as np

def createCosWorkspace(name,start,end):
        dataX = np.arange(start,end,0.1)
        dataY = np.cos(dataX)
        ws = CreateWorkspace(dataX, dataY, OutputWorkspace=name)
        ws = ConvertToHistogram(ws, OutputWorkspace=name)
        return ws

#create some histograms to test the algorithm with
ws1 = createCosWorkspace('left', 0, 12)
ws2 = createCosWorkspace('right', 3, 15)
ws3 = createCosWorkspace('right1', 6, 18)

ws4, sf = Stitch1D(ws1, ws2, Params=[0,0.1,18], StartOverlap=6.0, EndOverlap=12.0)
ws5, sf = Stitch1D(ws4, ws3, Params=[0,0.1,18], StartOverlap=6.0, EndOverlap=12.0)
plotSpectrum(['left', 'right', 'ws4', 'ws5'], 0)

ws6, sf = Stitch1DMany(InputWorkspaces='left,right,right1', Params=[0,0.1,18], StartOverlaps=[6.0, 6.0], EndOverlaps=[12.0,12.0])
plotSpectrum(ws6,0)

Example above has three identical cosine waves overlapping at x = 6 to x = 12.
