add a separate follow processor for helm

[mpedramfar]

Thanks for your great package!

Having helm-bibtex open as the follow processor is not ideal, since to take an action, we need to press tab and then not all actions are meaningful when point is on a citation. The PR adds a separate follow processor and two new variables, helm-bibtex-follow-actions-alist and helm-bibtex-follow-full-frame, to customize it. To use this processor, this should be added to the init file:

(org-cite-register-processor 'my-bibtex-org-cite-follow
  :follow 'helm-bibtex-follow)

(setq org-cite-follow-processor 'my-bibtex-org-cite-follow)

Hi and thank you. I can't test this right now. Could you please explain in one sentence what this follow processor does differently? And woudn't it be better to just replace the existing processor?

[mpedramfar]

Sure, but it's more than 1 sentence :)

In current setup:

1. After following a citation, the entry is only pre-selected, and user needs to select it again to take any action.
2. Not all actions are applicable for citations (I wouldn't want to insert the whole bibtex entry into a citation)
3. I prefer to have helm-bibtex take the whole buffer, but selecting from a few follow actions doesn't need the whole buffer.

This PR solves 1 and adds better defaults and customization options for 2 and 3.

And woudn't it be better to just replace the existing processor?

I'm not sure what you mean. This is exactly what this PR does!

[mpedramfar]

Actually it might be good to add

(org-cite-register-processor 'helm-bibtex-org-cite-follow
  :follow 'helm-bibtex-follow)

to the commit and then the user has the option of using this follow processor by adding

(setq org-cite-follow-processor 'helm-bibtex-org-cite-follow)

to their init file.

Looks good. Could you please also update the documentation here to reflect these changes? Thank you!

[mpedramfar]

Sure! I just made some changes. Let me know if there's anything else here I can change.
