NORMALISE_TO_MONITOR algorithm

[Nick Draper]

Once the unwrapping procedure has been implemented, all detectors and monitors should be on the same wavelength binning grid. It should be therefore straightforward to have an algorithm that divides the whole data set point by point by a given monitor spectrum. In fact, what we should do is the following: if the bin width array is

Bin_widths=[Dt1, Dt2…Dt_nchan]

Then

Workspace_norm=Workspace/Mon_spec*Bin_widths

In the implemented algorithm, we should be given a choice of several monitor spectra.

There should be other options to normalise by an integrated monitor count (over a specified wavelength range) rather than point-by-point.

Done, although it would be good to be able to select the monitor spectrum by name (requires 'dynamic parameters' since the names aren't known until the input workspace is set.
