so changed all algorithms that used it.

Touches nearly everything unfortunately but is necessary.

To reduce warnings when coord_t = float. Also, fix a warning #4473.

Merges multiple MDEventWorkspaces in memory. Will need some performance testing to tweak for optimal speed.

Refs #3984 Took the wiki description from every algorithm's wiki page and placed it in a comment in the CPP file (instead of the header file).

Refs #3724: Pulled wiki description text from the wiki site and added in algorithms' header file with special tags. The auto_wiki.py script can retrieve the text to generate the wiki page fully.

Refs #3724: wiki making in python script, wiki page validation, and a few descriptions that were missing from my algorithms.

Fixes #3543: Implemented MDEvent (with runIndex and detectorId). Added factory methods and macros to support it. CreateMDEventWorkspace can create either type of event workspace. Typedefs for MDEventWorkspace3 changed to MDEventWorkspace3Lean etc.

Fixes #3337: By making the BoxController always present in MDEventWorkspace, box IDs are now always generated correctly.

- Refs #2835: Added a MDDimensionStats object that calculates mean and approximate variance of positions.
- Refs #2835: Implemented a binary-tree style splitting for MDEventWorkspaces (MDSplitBox) as an experiment to replace MDGridBox.
- Added Utils::NestedForLoop routines.
- Refs #2711: Improved MDEventWorkspace binning speed by approximately 20 through better scheduling. Memory use is also much lower.
- Refs #2818: Fixed compiler warnings for MDEvents and MDEventsTest (as of last ~Monday with fewer warnings flags).
- More flags added to class_maker.py

Refs #2767: Deleted the API::Dimension object that was repeating what IMDDimension does. Changed MDEventWorkspace to use MDHistoDimension instead.

Refs #2012: Checkpointing code that is doing a good part of the work of eventworkspace->q-space conversion.

Refs #2572: Added an initDocs() for all algorithms that sets the summary string to display in the dialog, as well as the wiki summary for possible later auto-wiki-fication of documentation.
