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

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?

Xiaobo is working on the scientific/methods developments. Will contribute to Brainstorm tools updates when ready.
