DataFrame(read_from_sas) method that converts data loaded with SASLib.read

[xiaodaigh]

Currently conversion to DataFrame requires DataFrame(read_from_sas[:data]). Overload the DataFrame method so that DataFrame(read_from_sas) automatically converts feels more Julian.

Also can default to convert in the same column order e.g. define a new Type that is <: Dict{Symbol,Any} and call it the SASInput or something so it dispatch on the following

DataFrame(x::SASInput, colstable = true) = colstable ? DataFrame((c => x[:data][c]) for c in x[:column_symbols])...) : DataFrame(x[:data]);

I think integration with StatFiles.jl as proposed by @davidanthoff makes more sense. See comments from #2.

Yeah, I'm really impressed by the work in this repo, and essentially plan to switch StatFiles.jl over to use this package here once things are stable/settled down a bit. At that point DataFrame(load("myfile.sas7bdat") will just work, and the column order will be preserved. And of course it will not just work with DataFrame, but pretty much anything else (JuliaDB etc.).

@xiaodaigh The latest version makes the conversion to DataFrame a lot easier by using a standard two-argument constructor. Column orders are also preserved. I don't want to build yet another package dependency just for this so I'll leave it this way.

Closing this issue.
