[Orgmode] Generic LaTeX class support (scrlttr2/isodoc)

[Jambunathan K]

This is a follow upon my earlier posts in the following threads:

[1] 'Composing letters using org-mode and scrlttr2'
[2] Composingletters using Org mode and the LaTeX isodoc clas'

I am attaching four files
- org-latex-generic.el
- org-letter-utils.el 
- org-scrlttr2.el
- org-isodoc.el

Functionality is easily explained by usage rather than by words.

Usage Notes:

1. Load libraries
   - (require 'isodoc)
   - (require 'scrlttr2)

2. C-x C-f 'sample-letter.scrlttr2' and/or 'sample-isodoc.isodoc'. File
   extensions are important and they are indicative of the LaTeX classes
   targetted for export.

3. You will be offered a Org outline structure. Fill in the same. In the
   'To' address field you have an option just to insert a bbdb link as
   opposed to the whole address.

   Remember to fill in the LCO file for scrlttr2 and style file for
   isodoc.

4. Do a C-c C-e l or C-c C-e d.

5. See that your letter is nicely exported.

6. YMMV.

Additional Notes:

Files have helpful docstring. Core functionality is in
org-latex-generic-sectioning. Rest all are bells and whistles.

| environment, emit a LaTeX command, set optional arguments (with
| heading as key and entry body as value) and mandatory
| arguments. See `org-latex-generic-scrlttr2-sectioning-alist' and
| `org-latex-generic-isodoc-sectioning-alist'.

Watch Out For:

1. Have no empty lines in .scrlttr2/.isodoc file. If that doesn't help
   remove it from the generated tex file.

   I have a strong reason to believe org-latex.el is generating
   extraneous newlines in (org-export-latex-subcontent ...) at line 1029
   or thereabouts.

2. Have no commas in the bbdb address field. C-h f
   org-letter-utils-bbdb-export is probably not upto the task.

3. Remove \date directive in the isodoc tex file.

4. Also see FIXME notes in the org-latex-generic.el


Implementation Notes:

The key idea is to mirror the LaTeX commands in terms of Org
headlines. Start with C-h f org-latex-generic-sectioning for further
exploring. Try mapping the headline structure of .scrlttr2/.isodoc file
with the corresponding tex file and compare it against the settings of
of different variables in the org-scrlttr2.el/org-isodoc.el
