Various changes for checking if a vector is empty or not.

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 #3203: Implemented ISpectrum. It is the base class of EventList and Histogram and contains the spectrum number and list of detector IDs for a given spectrum.
- ISpectrum return X/Y/E vectors. EventList, e.g. calculates the histogram on the fly.
- Moved the EventWorkspace MRU list of histograms to be contained within the EventList; better code separation. Made a EventWorkspaceMRU class to encapsulate this more easily.
- Workspaces must implement getSpectrum (const/not const) to return a ISpectrum object. dataX(i), etc. methods on MatrixWorkspaces no longer need to be overridden since they call getSpectrum()
- Got rid of EventWorkspace::getEventListatPixelID() and doneLoadingData()
- replaceSpectraMap() methods offers backwards-compatibility with SpectraDetectorMaps by setting the specNo and detector list when called. Must be called AFTER creating all the spectra in a workspace.
- Refs #3318: maskWorkspaceIndex() implemented as part of ISpectrum.

Replace uses of the SpectraDetectorMap with the new interface. Note that mutableSpectraMap has now gone in favour of using MatrixWorkspace::replaceSpectraMap with a brand new implentation. Re #3067

Fixes #2666: new Progress reporter that prints to the console, for testing. Also, cleaned up the existing Progress class a bit.

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.

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

Improve performance of SumSpectra. The hinderance was the spectra remapping using the remap function, this is extremely slow. Changed to clear then add the relevent detectors as it go along. This reduces the time for summing a whole MERLIN data set from ~100 secs to ~1sec! Re #1694

First batch of algorithms with Workspace2D workspace properties changed to MatrixWorkspace. Re #1368.

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

Fix log memory leak and made loggers a bit more lightweight

loggers are now defined in the algorithm base class, sumspectra is the only one to take advantage of this so far.  Possible mild memory leak reintroduced need to look at the release of the logger in the alg destructor.

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

Add a spectra that sums all of the spectra in a workspace

re #351. A change to the workspace hierarchy. What used to be Workspace is now called MatrixWorkspace. New Workspace is a base class for MatrixWorkspace and TableWorkspace. TableWorkspace can be stored in AnalysisDataService and passed to algorithms as a property.

Modified Integration so that the user can specify an X range to integrate over instead of bin indices. Re #264.

Main change is the extension to the WorkspaceFactory 'create from parent workspace' method so that the caller can optionally specify a different size for the new workspace. Re #134.
