Even though before the error was okay, it wasn't clear to someone who didn't know about rebinning, nor was it always correct like in the case of "first boundary, width, last boundary, width, last boundary" as there are an odd number of boundary values.

The error now states that the number of parameters must be odd as this is what it checks for in the validator, and would mean that the correct number of boundaries is present.

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

Rebinning previously made sure that the very last bin was not less than 25% of the width of the penultimate bin. Now this check is applied at the transition between each range in a rebinning that has multiple binning regimes (i.e. the rebin parameter string has more than just 3 elements).
Also, added a check against zero bin width in the RebinParamsValidator. Re #1155.
