Allow parsing month abbreviations

[fangyi-zhou]

I was trying to use this library to parse my bib file, and encounted complaints regarding unresolved abbreviation 'dec', 'Mar', etc. Since many publishers use these abbreviations in exported bibtex, maybe it's a good idea to support them.

In the link you provided, it says:

Many BibTeX styles have built in macros that allow to use abbreviations

From my understanding, the month abbreviation are not directly in core language but in the bibtex styles themself. For example, the te.bst file defines those abbreviations as macros (ref).

Therefore, I am not inclined to include a change which is not included in the bibtex specification.

Doing the string abbreviation logic in this library was maybe a mistake. I see two approaches that need to be investigated:

• Passing a custom object to the parser to handle custom abbreviation
• Provide a raw parsing function which will return the bibtex object without resolving the abbreviation

What do you think?

Either solution is fine, the month macros are quite an oddity, but are used by some publishers when generating bibtex.

I personally prefer the first approach since it seems easier to configure.
