Let DataFrame automatically download the CSV

[hernanmd]

Currently DataFrame only expects a FileReference as parameter to create an instance:

DataFrame readFromCsv: '/dir1/dir2/myfile.csv' asFileReference

It could be a nice time saver to let the DataFrame actually "resolve" the parameter and download a CSV in a URL String transparently, for example:

DataFrame readFromCsv: 'http://path/to/url/myfile.csv'

I would prefer to have another method because else it means suddenly data frame is linked with Zinc.
Having a stream based API however could be nice to have

DataFrame readFromCsvOn: asStream

We can have something like this:

DataFrame >> readFromCsv: aFileReference.
DataFrame >> readFromCsvByUrl: aString.

df readFromCsv: '/dir1/dir2/myfile.csv' asFileReference.
df readFromCsvByUrl: 'http://path/to/url/myfile.csv'.

Cool, thanks!

I don’t think this is yet implemented. Should this really be closed?

You're right, I misread it "readFromCsvByUrl" and thought it was already implemented
