SaveNexus and SaveNexusProcessed wouldn't append a record to the history.
This commit fixes that issue and leaves a record on the input workspace so the result is that we get a
complete history, but we lose the execution start time and duration.

Some property orders in C++ have been altered such that the order in
Python stay the same.

Also add a unit test for this case.

Touches nearly everything unfortunately but is necessary.

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).

Make SaveNenux accept TableWorkspace, and make the File->Save->Nexus behave better when TableWorkspaces open. re #2425

Fixed tests outside NeXus/DataHandling that relied on loading data
Had to add Nexus as a link dependency for various package Test targets - don't know why!
refs #2822

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.

Refs #2572: Ran into issue with un-escaped characters that my compiler did not catch. Commented out all optional messages until I can fix it.

Fixes #2360: The problem was actually only in SaveNexus, it did not specify the start/end progress values so the progress was not updated at all.

Rename Framework code directory to just that. Also delete Main and VS & Eclipse project file. Re #1881.

Bumped FileProperty up to API so that it can take advantage of the new FileFinder. Code has just been moved here, not reimplemented yet. Re #1398

re #791,#792 added a new virtual function setOtherProperties.This is useful for setting the non workspace properties and period number when group members are processed.

Updated algorithms that were using the FileValidator class alone to use the new FileProperty class. Re #767

re #774 - Renamed algorithm properties - SpectrumIndex to WorkspaceIndex,StartSpectrum to StartWorkspaceIndex,EndSpectrum to EndWorkspaceIndexAlso changed X axis  of 1D graph  from Spectrum to WorkspaceIndex

re #697, re# 698 loading and saving workspace groups for nexus files. Roman is fixing the LoadISISNexus failure.  

re #605 implemented progress reporting for all algorithms.Parallel processing implemented for some algorithms - it was not applicable for all algorithms

Remove redundant loggers from Nexus project

Please point out if any descriptions could be better or more helpful.  Descriptions for nearly all properties in the documented algorithms in the algorithm directory are now in, work continues on those in datahandling.  I still expect to finish sometime on Thursday.  refs #410

There maybe still be bugs due to changes to PropertyManager and isDefault() but I've checked all he isDefault() functions now refs #593
