F_AlignToCornerPin

Adds an 'Export' tab to F_Align nodes to export corner pins

Currently two modes are available:

1. baked - copy keyframes so you can delete the F_Align node afterwards
2. linked - use expression links to keep the cornerpin connected to the F_Align node for further tweaks,

To install place F_AlignToCornerPin.py in your plugin path and add the following line to your menu.py (this will automatically add the required code and user knobs next time Nuke is launched):

import F_AlignToCornerPin
