Handle csv

It would be useful to handle simple csv file.
A "schema" in that case would be a header row, e.g.

simplest can be:
name:string,success:bool,value:float
or even
name:string,value:float

And result output can then be
test1,10.1
test2,10.2

etc.

Since generating and reading csv files is "easy" that will make help usability of the plugin.
