Filter events by fast log value from pre nexus file

[Wenduo Zhou]

Fast log values are recorded in event pre-nexus file with special pixel IDs. Therefore, for this type of log value, event filtering can be made from pre nexus data.

This algorithm will serve to prove the result obtained by the regular event filtering algorithm acting on event workspace. And it will serve as a benchmark for processing speed.

But this algorithm is just a prototype and is not supposed to be used by Mantid users. It will inherit from DeprecatedAlgorithm.

Started FilterEventsByLogValuePreNexus. Refs #8655.

New algorithm was copied from LoadEventPreNexus2.

[Wenduo Zhou]

Make algorithm deprecated. Refs #8655.

1. Algorithm is made deprecated because it is used to verify

FilterEvents on fast sample logs;

2. Fixed a bug in compiling.

[Martyn Gigg]

There is a compiler warning about an unused variable in ​FilterEventsByLogValuePreNexus.cpp and also a ​cppcheck error

[Wenduo Zhou]

Fixed cppcheck error and compile warning. Refs #8655.

Changeset: ac1bb4289561c34e7f3af555add298ea595f7a40

[Martyn Gigg]

Unfortunately the same cppcheck error still exists. I don't quite understand why the same line later in the file doesn't cause the same error but I think it's a false positive so can be supressed by putting

// cppcheck-suppress syntaxError

on the line directly before the #PRAGMA_OMP.

The same problem also exists in GenerateEventsFilter.cpp at line 1367

[Wenduo Zhou]

Suppress a cppcheck error. Refs #8655.

There are 2 ​doxygen warnings coming out of FilterEventsByLogValuePreNexus.

[Wenduo Zhou]

Refs #8655. Fixed 2 doxygen error.

For tester

The purpose of this ticket is to generate an algorithm to verify GenerateEventsFilter and FilterEvents operating on fast sample log. Therefore, algorithm FilterEventsByLogValuePreNexus is a deprecated algorithm, which means that it is not supposed to be used by most users.

The most efficient way to verify this ticket is to filter events from a preNexus data file and compare the result from GenerateEventsFiler/FilterEvents.

1. Download the script verify8655.py;
2. Merge the commits from this ticket and build Mantid;
3. Run script;
4. The difference between 2 binned and reduced workspaces, recorded by workspace Diff20002, are tiny. Only 3 counts are in difference out of millions.

[Wenduo Zhou]

Added a unit test. Refs #8655.
