Adding a Refractory Period Violation number somewhere

[Pierre Yger]

How easy is it to add an extra column to the ClusterView? Because I saw you added the firing rates, which is great, but what about Refractory Period Violation? I.e. what are the percentage of spikes (among all the spikes for a given units) such that the interspike interval is below a certain number (2 ms for example). This is something quite useful, to quickly identify MUA (since they have high level of RPV).
And more generally, are columns hard-coded somewhere, or is there a way to provide custom functions for sorting the cells?
