It seems I should have specified the frame in the connection form as well
as in the display (object? - I have no idea about OOP having been a
functional programmer for the last 30 years).
In [13]:
omega(0,0,e).display(e), omega(0,1,e).display(e)
Out [13]:
(nabla_g connection 1-form (0,0) = 0,
n
Well apparently I should *not* be using `connection_form` but instead
`gam_e = nabla.coef(e)`
`gam_e[:]`

Which is what I would have expected. I'm still confused by what
`connection_form` does if it doesn't calculate the connection forms.

That should be
`omega(1,1).display(e)`
