[wip-cite-new] Quick note about citation insertion

[Nicolas Goaziou]

Hello,

I just added an interface to unify functions responsible for inserting
citations in a buffer. The default binding is <C-c C-x @>.

I also plugged a rather crude function with that interface. In order to
use it, you can evaluate:

  (setq org-cite-insert-processor 'basic)

Internally, this will bind <C-c C-x @> to `org-cite-basic-insert', which
can insert citations, or edit existing ones, depending on the point.

>From a developer point of view, you can specify two new keywords when
registering a new processor: :insert and :cite-styles. See
`org-cite-register-processor' for details. See also an application in
"oc-basic.el", for example.

Regards,
