Legend for spike amplitude view

[acomrie]

Would it be possible to show a legend for the units displayed in the spike amplitude view? I recall such a legend from qt-mountainview. Could simply display the colored dot and the unitID. A legend overlapping the plot could block view of the data, so perhaps a legend could fit underneath the x axis, to the right of the time range display - where I think there is currently some unused space. If more than a handful of units are displayed in the same spike amplitude view, the legend may become too large and may interfere with the plot itself - perhaps then it could just go away (that is, only display the legend when, say, <10 units are selected or something). Not especially high priority, but will help make the spike amplitude view more readable when plotting multiple units at a time. Will also help user identify times when two units are assigned the same color marker in the plot. Thanks!

Great suggestion. Putting as medium priority.
