IntChron parser prototype

[joeroe]

This was an initial prototype of a parser for IntChron. Following discussion in ropensci#115, we decided to leave interacting with IntChron to another package (rintchron https://github.com/joeroe/rintchron) and use this to write separate parsers for each individual database indexed by IntChron.

@joeroe do you think we can revitalize this? I stated some crude work on ropensci#147 in order to finally takle ropensci#115 . It would be great to (again) get your view & input in how best to integrate Intchron via your package.

Yeah, I was actually planning to work on rintchron again next week in relation to https://github.com/xronos-ch/.

As I recall, the core functionality is there, and the remaining issues relate to adding additional query functions (not really relevant to c14bazAAR), and making the response parsing more robust (probably the problem you are running into in joeroe/rintchron#13!) I'm aiming to submit it to CRAN after those are fixed, at which point I think rintchron can be a reliable dependency for c14bazAAR.

Here you can see how I envisaged a parser for an IntChron database looking: https://github.com/joeroe/c14bazAAR/blob/c2031d41101d12f50a838a5a28817b56778974e6/R/get_oxa.R – simple and almost the same as yours. The only problem is the extreme slowness of getting an entire database from IntChron compared to flat-file databases, the unfortunate tendency of the IntChron server to occasionally fail for no reason. However as I remember @nevrome thought this shouldn't stop us adding it to c14bazAAR.

I am looking forward to see a CRAN release of rintchron. And despite some waiting time, I think the databases to be queried are worth that. So many thanks for keeping your package up and us in the loop.
