on RHEL-6

The solution (setting bin width to 1.0) is admittedly arbitrary, but in
lack of more information it seems to be the only solution (apart from
throwing an exception).

Add rigorous tests for it as well.

And use a standard algorithm instead of home-brewing it.

Includes basis for creating a simulation workspace, the fitting function itself and the TobyFit
resolution model.

Since VectorHelper::rebin() requires current X vector with
one more entry than the current Y vector, even if the
Workspace2D is a distribution, we need to adjust the current
X vector before calling rebin.  This is a convenience method
that essentially reverses the convertToBinCentre() method, so
it seems to belong in VectorHelper.

Fixes #3351: test for VectorHelper and some refinement of that method to split a comma-delimited string. Refs #3349: BoxController XML serialize/deserialize.

Flatbackground now works for non-distribution data and SANS Display Mask is now clearer re #2612 fixes #2599

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

Refs #1622: StripVanadiumPeaks algorithm added. Added a couple of VectorHelper functions for finding bin indices and for splitting a string into a vector. Made FindPeaks use those too.
