URL as input for r.unpack and v.unpack

[wenzeslaus]

The following modules accept a local file as input parameter, they could also accept a general URL (similarly to G7:g.extension) and download the archive from the Internet.

• G7:r.unpack
• G7:v.unpack

The would be helpful in cases when users needs to use a file stored somewhere online. The whole thing could be done in one step (from GUI or command line) if input='http://example.com/araster.pack' is supported.

There is no equivalent of r.pack-r.unpack for 3D rasters or imagery groups, but there are "import" modules for temporal datasets which can potentially use same improvement:

• G7:t.rast.import
• G7:t.vect.import

Possible criticism: There are many modules which just take a file (as opposed to more complicated inputs like in G7r.in.gdal/G7r.import) for example G7:r.in.xyz or G7:v.in.ascii which can use the same, but they are in C, not in Python, and adding this functionality would be much more complicated. Hence, it is clear that the proposed features depends on the language used for implementation, not purely on design decision.
