Create spectroscopy-letters

I've started working from the applied spectroscopy style as mentioned in the summary. 
There are still a few issues, but at least it seems to be compliant to 100% with journal references
Issue: a comma after the date still appears in the book references and I didn't know how to remove it. Probably it works with conditionals...)
Update spectroscopy-letters

Hi there!

I've done the changes as follows:
- .csl in the ID (line 7) but I don't see the extension in the ID codes of other styles...
- Documentation address is now http://www.tandfonline.com/action/authorSubmission?journalCode=lstl20&amp;page=instructions (line 9)
- Both ISSN updated
- and the changes proposed by zuphilip regarding the comma are also done. I tested it and now it looks very nice!

Thank you guys!
Update spectroscopy-letters

Just modified the summary
Update and rename spectroscopy-letters to spectroscopy-letters.csl

OK!
Also removed .csl in the <id>
Update spectroscopy-letters.csl

In Book reference: changed comma to colon between publisher and place
Update spectroscopy-letters.csl

Here I put back on line 108 to <text macro="year-date"/> to at least have the date appear
Also changed in an ID line 10 "applied-spectroscopy" to "spectroscopy letters"
Now I'll see what I cand do with the CSL Editor to improve the style
Update spectroscopy-letters.csl

Now I worked again with the CSL Editor online.
Several issues have been checked and I copy-pasted the whole code again.
Update spectroscopy-letters.csl

In book chapter: 
- switched editors and book title --> seem to be OK
- Tried to move the In prefix to the book title (container-title macro) --> it still appears before the editors
Update spectroscopy-letters.csl

- Switched the position of text variable="In" from the editor to before the book number
- Added <else> code </else> as proposed by zuphilip in the publisher macro
Update finanzarchiv.csl

Add pages in chapter/inproceeding (forgot before)
Add new style for JITE

... JITE = Journal of Institutional and Theoretical Economics.

This style looks quite similar to the Chicago Manuals Style, but they don't mention anything in their style guide.
Update spectroscopy-letters.csl

Changed the template name back to applied-spectroscopy
Added name of co-authors who helped me with the code
Update journal-of-institutional-and-theoretical-economics.csl

I guess "& #8212;" is better than "-", also I don't understand the difference exactly.
Create INSPQ-NAPP.csl
Create INSPQ-TOPO.csl
Update finanzarchiv.csl
Update leviathan.csl

The style changed very much since 2012. The update is more or less a rewrite of the Leviathan style which should implement the current style guidelines (I checked the guide lines I received and 3-4 current articles). More details:
 * I implemented only the things which are either mentioned in the style guide or I have seen (consistently) in current articles (e.g. collection-title, translators, doi are not implemented). 
 * I updated the quotation marks according to the current articles (also the style guide uses different quotation marks).
 * The URL is at the moment only shown for articles in magazines and newspapers, because I have seen that in current articles (style guide does not say anything about that).
 * References to webpages are very confusing: the hints in the style guide are not what I have seen in current articles, and that was not always consistent. It seems also that references to webpages are given in the footnote but not listed in the bibliography, which would mean AFAIK that one has to do that anyway manually (or with the export function).
 * Although most references are given in footnotes, it is mentioned in the style guide: "Bei bloßen Literaturhinweisen ohne Zitat in den Fußnoten [...]". Therefore, I left the category to "author-date" and did not change it to "note", but I am not sure about that.
 * The style supports originalDate correctly, whenever this will be possible in Zotero.
