Description
-----------

Two :ref:`TimeSeriesProperty` logs are merged together
by the time stamps.

Output
------

A MatrixWorkspace.


Usage
-----

**Example - Merge 2 sample logs with value reset:**

.. testcode:: ExMerge2Logs

  Load(Filename=r'HYS_11092_event.nxs',OutputWorkspace='HYS_11092_event')
  MergeLogs(Workspace='HYS_11092_event',LogName1='Phase1',LogName2='Phase2',MergedLogName='PhaseM12',ResetLogValue='1',LogValue1='1',LogValue2='2')
  ws = mtd["HYS_11092_event"]
  newprop = ws.run().getProperty("PhaseM12")
  prop1 = ws.run().getProperty("Phase1")
  prop2 = ws.run().getProperty("Phase2")

  print("Phase 1's size = {}, Phase 2's size = {}, Merged size = {}.".format(prop1.size(), prop2.size(), newprop.size()))
  for i in range(5):
      print("Phase1              Time[{}] = {}.".format(i, prop1.nthTime(i)))
  for i in range(5):
      print("Phase2              Time[{}] = {}.".format(i, prop2.nthTime(i)))
  for i in range(5):
      print("Mixed Phase 1 and 2 Time[{}] = {}.".format(i, newprop.nthTime(i)))

.. testcleanup:: ExMerge2Logs

  DeleteWorkspace(Workspace='HYS_11092_event')

Output:
