barbs not work in 0.9.0 version

[wangrenz]

Hi luke:

Barbs reported an error in version 0.9.0.

plot barbs code as:

axs[0].barbs(ds.lon, ds.lat, ds.u.sel(lev=p_lev), ds.v.sel(lev=p_lev),regrid_shape=35,
        sizes=dict(emptybarb=0),length=4, lw=0.3,pivot='middle', barb_increments={'half':2,'full':4, 'flag':20})

Result as follow:

 axs[0].barbs(ds.lon, ds.lat, ds.u.sel(lev=p_lev), ds.v.sel(lev=p_lev),

AttributeError: 'Barbs' object has no property 'markersize'

Old 0.7.0 version works well.

Thanks

Thanks, this was a one-line fix (fe7b2d1). sizes was getting translated as markersize in an attempt to make the line-markersize property markersize consistent with the scatter-collection markersize property sizes. And this meant a keyword conflict with barbs. I've removed this translation.
