- 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.

Refs #3157 Sort our System.h. It was becoming a dumping ground. It should only be touched when absolutely necessary as it affects every file in Mantid. Also combined this with Refs #2345 to sort out DLLExport/DLLImport usage. It's done for Kernel, Geometry and API but stuff in the plugins could do with updating as well.

Removed check for the executable name from the ConfigService. It now either uses the path pointed to by MANTIDPATH or the executable's directory if the former is not set. Also renamed a couple of functions relating to this so that it is clearer what their return values point. Re #2256

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

Sort out const correctness surrounding IInstrument::getPlottable. Also clear a bundle of compiler warnings. Re #990.

re #928 Added optional parameter to control the loading of monitors and creates separate workspace/workspace group for monitors.

ISISRAW2 code maintainability drastically improved

Outputting files now differs under Windows and Linux. Linux now uses a directory under the user's home directory, $HOME/.mantid, to store things such as mantidsimple, logs, managed workspace files. This is basically so that the 
installation via the RPM can work properly. Windows behaviour should be unchanged. Re #587  

Eliminated the variant of Workspace2D::setX/setData that takes a const reference to a vector and then copies it inside. This is inefficient since the vectors already exist once the workspace is initialized. The correct way is to take a reference to the MantidVec and assign directly to that. Re #558.

A few other code documentation warnings removed

Changed handling of working directory so that if we are running through Python then the initial working directory is that set by Python. Closes #434. 

Changed any usage of hard-coded relative paths so that they are translated into absolute paths using the directory of the executable as the bsae directory. Re #404

ManagedRawFileWorkspace2D checks the speed of data input from the raw file. If it's too slow because the file is on a network disk a cache file on the local drive can be created. A new property called "Cache" is added to LoadRaw2 algorithm. It takes values "If slow", "Always" and "Never" which mean create cache if connection is slow, create anyway or don't create in any case. re #304

Improved thread safety for ManagedRawFileWorkspace2D, re #190. Improved the look of MantidMatrix, re #272

Changed LoadRaw2 to load instrument into ManagedRawFileWorkspace2D. Added LoadRaw2Test and ManagedRawFileWorkspace2DTest. re #190

Added ManagedRawFileWorkspace2D workspace which does not load the data into memory until it is needed. LoadRaw2 and MantidPlot are modified to use it. re #190
