Guess formatting

[lukas-rokka]

As I wrote on email earlier, I think it would be cool if shinypod could make an initial guess of how the flat file is formatted. I've now put together a package that does that

https://github.com/lukas-rokka/readrGuess.

It simple runs trough different options of formatting the delimiter, decimal mark and grouping mark and chooses the combinations that creates a data frame that make most sense.
