1. @ukmo-ccbunney added new cube component convenience methods that allow for manipulation of any named dimensional component that can be attached to a cube (i.e. coordinates, cell measures and ancillary variables) via a common interface. The following methods are provided:

   • component() and components(): get one or more components from a cube

   • add_component(): add a component to a cube

   • remove_component(): remove a component from a cube

   • component_dims(): return the cube dimension(s) spanned by a component.
