View CSV columns in separate vim buffers in vertical splits

[mechatroner]

This would be especially useful for multiline CSV fields.
This also could be useful for very long (oversized) textual fields even if they don't have newlines in them - in a separate buffer they can be line-wrapped by Vim - in this case, one record would correspond to multiple screen lines.
The following commands would be also required:

• Extract current column into a separate vertical split buffer - will create at most two new buffers: to the left and to the right from the current column.
• Show current logical row (record number)
• Sync rows (in all vertical csv buffers jump to the physical lines that correspond to the logical row in the current split buffer)
