Adding:

`draw_basins': Function to plot river basins with their discharge vector and basins id (from 'routing.nc')
`draw_river_desc': Function to plot rivers' description from ORCHIDEE's routing scheme
`draw_subbasin': Function to plot subbasin from 'routnig.nc' ORCDHIEE
`vectors': Function to plot wind vectors

Improving: `vectors'
