Optical Flow Update and Helmholtz Hodge Decomposition Enabling

[LeoNouvelle]

Hello,
Here are the changes I commited in my pull request:

Minor code updates and corrections on:

• panel_opticalflow
• bst_opticalflow_states
• bst_opticalflow

Enabling Helmholtz-Hodge Decomposition:

• panel_opticalflow (gui perspective)
• bst_opticalflow_hhd (new function, maths)

Thanks,
Léo

This is already only executed when the displayFlag is set, why the need to uncomment this for debugging?

Thank you Leo for your update. You are only modifying files related to the optical flow so this is a pretty safe merge. Were you planning on writing a documentation for your changes? This would greatly help us test this.

Some minor comments right off the bat:

• The GUI freezes and it takes a long time to compute after you click on a big source file and go to Plug-Ins -> [Experimental] Optical flow. Is it possible to add a progress bar to tell the user a computation is happening so they know their computer is not frozen? Refer to bst_progress.
• Some code is commented out without explanation
• There are some comments in French in the code ;)

Great work!
Martin

@LeoNouvelle
Is this PR still a work in progress?
