Understand why Mantid cannot read PSI Nexus file

Description

See Steve's comment below. The example PSI Nexus file can be copied from
Olympic\Babylon5\Scratch\Anders\lem11_his_3420.nxs (to big to be attached to ticket)

Steve writes: Part of our EU JRA work, in collaboration with PSI, involves working towards a common exchange data format for muon data using NeXus. They have written a converter to our '.v1' format. There's still quite a lot missing from the files, but when I attempt to load one using Mantid I get the message: Error in execution of algorithm LoadMuonNexus: vector<T> too long Because they have much better timing resolution when compared to ISIS the histograms are much longer - 66600 bins in this example compared to our usual 2000. I'm guessing, therefore, this is the problem. If so, I suppose it's not a hard limit as the files are quite small and HDFView happily reads the data. Alternatively, perhaps this error is misleading and originates from some other badly formed entry in the file.
