Generate events filters by various time steps

[Wenduo Zhou]

In some case, the user wants to split the events along time with various time steps but not a constant time step that is the only supported format now.

Thus add a new property for various time steps.

Refs #11112. Modified the property TimeInterval.

Such that it can take a list of doubles instead of 1.

• modified: ../Mantid/Framework/Algorithms/src/GenerateEventsFilter.cpp
• modified: ../Mantid/Framework/Algorithms/test/GenerateEventsFilterTest.h

• modified: ../Mantid/Framework/Kernel/src/InternetHelper.cpp:

the cast of osstringstream to osstream on mac osx. Modify it only to make the compiling pass.

For tester

1. Check whether any system test and unit test gets failed due to the change of input property 'TimeInterval';

2. Find an event Nexus file, such as PG3_9829_event.nxs in system test. Then run GenerateEventFilters by setting TimeInterval to a few numbers for various lengths of splitters. Then check whether the output SplitterWorkspace has the correct output. You may also run FilterEvents from the result with option 'SplitLogs' on. It is easy to check the sample logs such that they are split as you expect.

Fixes issue #11112(​http://mantidproject.org/mantid/ticket/11112)

The changes is to enable GenerateEventsFilter to generate splitters with various time intervals. Besides the documentation of this algorithm and unit tests are updated for the new feature.

Could you update the pull request title remove the ticket number, following the guidelines [here](http://www.mantidproject.org/Git_Workflow).

Not really part of this ticket, but very related, I was checking the wiki page on event filtering (http://www.mantidproject.org/EventFiltering) and I noticed that there are many outdated links. It would be a good idea if someone familiar with this would have a look at it and bring it up to date.

[Federico M Pouzols]

It all looks good to me, and well documented. GenerateEventFilters and FilterEvents behave well. Unit and system tests pass.

Somehow these slipped through without a resolution. Set to Fixed.
