NdLayout opts undoes cols

[jordansamuels]

It appears that calling .opts() on an NdLayout will undo the effects of .cols(). E.g.

c = hv.Curve(np.arange(3))
hv.NdLayout([(n,c) for n in range(5)]).cols(2).opts(plot=dict(title_format="> 2 columns"))

results in

The does not appear to be a problem with Layout.

I suspect NdLayout needs a clone method that preserve cols, the way Layout does it:

    def clone(self, *args, **overrides):
        """
        Clone method for Layout matches Dimensioned.clone except the
        display mode is also propagated.
        """
        clone = super(Layout, self).clone(*args, **overrides)
        clone._max_cols = self._max_cols
        clone.id = self.id
        return clone

Not sure why the id isn't propagated by the super call here but that is separate from what is important for this issue, namely transferring the value of_max_cols.

Now fixed, closing.
