Vetala Beta 0.4.7.1

[louisVottero]

• util_file.fast_copy added, in windows uses windows' robocopy to copy many folders/files faster
• util_file.copy_dir now uses fast_copy when no ignore_patterns are given.
• process auto completion now uses AST like the other code, making it much easier to see what's available and how to set process functions.
• pre and post process.run_script are now using decorators for cleaner code and to ensure that the right code runs
• When running code through process.run_script the selection no longer clears automatically. This allows option scripts (buttons) to work on selected
  
  Added
• core.viewport_off to toggle the viewport 2 on and off
• core.delete_set_contents added, deletes everything in a set
• core.get_hierarchy_by_depth will get the hierarchy in order of how deep it is in the hierarchy. First children returned first, followed by second children, etc.
• core.get_hierarchy does cmds.listRelatives ad = True and then does a reverse on the result. This makes the result reflect depth order a bit better.
• attr.clear_multi resets a multi attribute to no indices
• attr.append_multi_message appends an input to the end of a multi attribute
• rigs_util.create_distance_reader now has the option to go negative for when its moving in the opposite direction. The weight value it creates will then from -1 to 1 instead of 0 to 1.
• space.get_longest_aligned_vectors given a mesh this will return 2 vectors that can be used to create 2 joints at the to farthest ends of a piece of geo. Good for rigging props
• attr.set_color_value sets the value component (hsv) but given an rgb color. This is meant to help modulating rgb control colors
  
  Rigs
• scaleConstraint is being used with targetParentMatrix disconnected. This works similarly to how it was working before with scale channels connected directly. However the scaleConstraint does a bit of extra work that deals better with joints being scaled in different ways. It solves a couple of use cases but not everything.
• In some cases SparseRig now respects scaleCompensate being off. It may not work if the scale is negative though.
  
  Fixes
• space.scale_constraint_to_local now keeps offsets better
• deform.smooth_skin_weights now has the option to use the api. Not using the api is more reliable and has undoability. This is also reflected in the ui.
• sometimes process that were current in the ui were not updating in the Data and Code tabs
• Data widgets now expand contract like they used to ages ago.
• qApp wasn't loading properly in Maya 2020
• rigs_util.Control.set_curve_type fix when color is rgb. It will keep the rgb on the new curve instead of erroring.
• deform.find_all_deformers is now fixed when a mesh has no history

There was a fix in Beta 0.4.7.1 that sees Vetala working with Maya 2017 again
