/** Takes a workspace as input and rebins the data according to the input rebin
parameters.
Required Properties:
<UL>
<LI> InputWorkspace - The name of the workspace to take as input. Must
contain histogram data. </LI>
<LI> OutputWorkspace - The name of the workspace in which to store the
result. </LI>
<LI> RebinParameters - The new bin boundaries in the form
X1,deltaX1,X2,deltaX2,X3,... </LI>
</UL>
The algorithms used in the VectorHelper::rebin() and
VectorHelper::createAxisFromRebinParams()
are based on the algorithms used in OPENGENIE /src/transform_utils.cxx
(Freddie Akeroyd, ISIS).
When calculating the bin boundaries, if the last bin ends up with a width
being less than 25%
of the penultimate one, then the two are combined.
