VioletteChiara/AnimalTA: AnimalTA v2.3.1

This update is a minor update that will bring little changes to the program.

It induces the introduction of some new features and some bug fixes.

I) New features

• AnimalTA now proposes to make manual trackings: fill the table with NA values and let the user make the tracking manually.
• Now when a shape (ellipse, rectangle, polygon) or a circle is defined in the analyses, the program calculates various variables for the trajectories inside those shapes (i.e: speed inside the shape, prop time stopped inside, etc)
• Concatenation of concatenated videos is now possible.
• Export a video will now adapt the frame rate of the exported video to the reading speed defined by the user in the "export video" section.

II) Bugs correction:

• If the videos were concatenated but not cropped, the tracking was not functional. --> fixed
• When using the "redo the track" option, the displayed frame after validating was not the correct one if the video frame rate was not the original one. --> fixed
• The meander value was underestimated by previous calculations. --> fixed
• The tracking process was sometimes especially slow (hours for a few minutes video). --> fixed
• It was sometime impossible to copy or rotate some arenas. --> fixed
