Monte Carlo is used as the general (fallback)s method. Also, code for
the triangular mesh case is included, but unused. The way we create
surfaces now doesn't produce consistent surface normal directions. This
makes the triangular method fail.

Re #19154

This allows for `material` not to be involved in the majority of
mantid source files.

Refs #3175. Sorry for the huge commit but certain things require Matrix to be in Kernel. Given how Quat, V3D and Matrix inter cooperate it seemed sensible for them to be in the same place and arguably this is where they belong anyway.

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.

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

Adding the SampleEnvironment class plus changes around Geometry for the Monte Carlo work. Some changes in Geometry just clear warnings surrounding unitialized objects in copy constructors for class with virtual base classes. Other changes revolve around materials. Re #1212

Altered slightly how the ray tracing framework and tracks in general accumulate their intersections results to improve the performance of tracing. Also altered Object bounding boxes so that they are no longer created with the new operator. Re #1212

Removed unused material fields from Object class, Re #1735

Added a BoundingBox class and implemented caching at the CompAssembly level. Note that there are still several functions using the old getBoundingBox methods but this covers a lot of the needed code for the MC correction. Re #1212

Visual Studio 2010 project updates. Added two property files that contain definitions that are shared across the multiple projects defined within the solution. This saves defining, in particular, preprocessor directives in every project.
Also update Geometry code so that the headers can be included without having to find and include other headers first. Re #1389

Add an algorithm to calculate absorption corrections for a generic sample shape. Algorithm name is AbsorptionCorrection, the class name is AnyShapeAbsorption. This also required changes to the Sample and Object classes because the sample shape object wasn't being copied properly. Re #1123.
