support for csv files

[vapniks]

I think it would be very useful for to have support for .csv files as this is a very common file format used by data analysts.

You might want to try our fork. As you can see in the documentation, "-d," can be used to interpret commas as delimiters, like cut does. It will successfully parse simple csv files such as

1,2,3
4,5,6

...but not complex versions such as

1,2,"foo"
1,2,"foo, bar"
