Convert int to string in such a way that RHEL6/7 are happy with the conversion

Changed from TS_ASSERT_EQUALS to TSM_ASSERT_EQUALS and involved the loop
variant in the failure message to identify which Histogram produced the error.

forgot to do this before formatting with clang

Removed any redundant includes from ConvertToMatrixWorkspace.h.
Changed any use of AnalysisDataService to use Mantid::API::Algorithm instead
Reformatted using Clang format

Reduced dependencies on name spaces and ordered header files to comply with
coding standards

Changed header file to use in-memory workspace instead of file

Refs #2899

by using the ADS::retrieveWS<Type>() method.

- 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.

Fixes #2091: equals() function for quickly comparing workspaces. == operator cannot be overloaded since it compares the shared pointers rather than the actual contents.

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