- Support for additional Read/Write node option 'raw'
- v2.1:
- Fixed bug where Read node always got premultiplied
- Support for ../ in filepath/expression
- Dialog on 'filepath not found' error

variable)
- General cleanup of various methods for greater maintainability
- v2.0:
- Completely rewritten from scratch
- Improved detection of frame range
- Supports any padding format (not only %04d)
- Applies colorspace to Read node
- Supports not only Write nodes (see FILEPATH_KNOBS variable)
- Supports definition of 'single file image sequence' formats
(see SINGLE_FILE_FORMATS variable)
- PEP8 compliant!

Usage:
Select any Write node and run ReadFromWrite() after having sourced this
file, or put the following in your menu.py:

import readFromWrite
nuke.menu('Nuke').addCommand('Read from Write',
'readFromWrite.ReadFromWrite()',
'shift+r')

Please note:
Script is now started via ReadFromWrite() instead of the old
readfromWrite() function, so you'll have to update your scripts if you
are updating from a 1.x version.

Still untested in Linux. Let me know if it works there and if so, I can tick the 'Linux' checkbox.
