Tooltip feature in @grainBoundary plot function

[eugenianietov]

It would be very useful to have the tooltip function available in grain boundary plots, so we can access property values from a plot, i.e. the exact value of the misorientation angle in a certain grain boundary. I have noticed that this capability is available in the @grain2d plot function, but it is not in that of the @grainBoundary class. I have tried to modify the plot.m function myself, but it is way beyond my Matlab programming skills.

The kind of plot in which I would like to obtain the value of a property in a grain boundary would be something similar to the plots shown in the Boundary Plots section of the documentation https://mtex-toolbox.github.io/BoundaryPlots.html. Thanks in advance for your time!!
