Add a test for MergeCalFiles

[Nick Draper]

There is no automated test for this algorithm. Here is a possible test script.

The last 2 calls in this test script fail with "Unknown exception":

CreateGroupingWorkspace(InstrumentName="PG3",GroupNames="bank124,bank144,bank164,bank184",OutputWorkspace="pg3_group")
LoadCalFile(InputWorkspace="pg3_group",CalFilename="/home/8oz/Code/Mantid/Test/AutoTestData/pg3_mantid_det.cal",MakeGroupingWorkspace="0",MakeMaskWorkspace="0",WorkspaceName="pg3")

w = mtd["pg3_offsets"]
for y in xrange(10000):
	w.dataY(y)[0] = y*0.00001
	
SaveCalFile(OffsetsWorkspace="pg3_offsets", Filename="pg3_offsets.cal")
SaveCalFile(GroupingWorkspace="pg3_group", Filename="pg3_group.cal")

def check_result():
		LoadCalFile(InstrumentName="pg3", CalFilename="pg3_merged.cal", WorkspaceName="pg3_merged", MakeGroupingWorkspace=1, MakeOffsetsWorkspace=1)
		print CheckWorkspacesMatch("pg3_offsets", "pg3_merged_offsets", Tolerance=1e-5)

MergeCalFiles(UpdateFile="pg3_offsets.cal", MasterFile="pg3_group.cal", OutputFile="pg3_merged.cal", MergeGroups=0, MergeOffsets=1, MergeSelections=0)
check_result()

for mergeGroups in [0, 1]:
	for  mergeSelections in [0, 1]:
		MergeCalFiles(UpdateFile="pg3_offsets.cal", MasterFile="pg3_group.cal", OutputFile="pg3_merged.cal", MergeGroups=mergeGroups, MergeOffsets=1, MergeSelections=mergeSelections)
		check_result()


# These fail with UNKNOWN exception!
MergeCalFiles(UpdateFile="pg3_group.cal", MasterFile="pg3_offsets.cal", OutputFile="pg3_merged.cal", MergeGroups=1, MergeOffsets=0, MergeSelections=0)
MergeCalFiles(UpdateFile="pg3_group.cal", MasterFile="pg3_offsets.cal", OutputFile="pg3_merged.cal", MergeGroups=1, MergeOffsets=0, MergeSelections=1)

For reference see #3198. Janik raised the need for a test script.

A test is already present. and I can confirm that the above script now runs without errors.

[Mathieu Doucet]

A system test that uses this algorithm does exist. The algorithm should be moved to the new python API though.
